The CData Sync App provides a straightforward way to continuously pipeline your CSV data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.
The CSV connector can be used from the CData Sync application to pull data from CSV and move it to any of the supported destinations.
The Sync App models local CSV files and remote CSV APIs as bidirectional tables. In addition to processing CSV data, the Sync App also abstracts authentication, HTTP, and SSL/TLS: The major authentication schemes are supported, including HTTP Basic, Digest, and NTLM. The Sync App also facilitates connecting to data sources that use the OAuth authentication standard.
The CData Sync App is designed for streaming CSV only.
This streamed file content does not include all of the metadata associated with remotely stored CSV files, such as file and folder name.
If access to both the file metadata and the actual file content is needed, then the CData Sync App must be used in tandem with the associated file system driver(s) for the service the CSV files are remotely stored in.
The following file system drivers are available:
See the relevant CData file system driver's documentation for a configuration guide for connecting to stored CSV file metadata.
For required properties, see the Settings tab.
For connection properties that are not typically required, see the Advanced tab.
The CData Sync App allows connecting to local and remote CSV resources. Set the URI property to the CSV resource location, in addition to any other properties necessary to connect to your data source.
Set the ConnectionType to Local. Local files support SELECT\INSERT\UPDATE\DELETE.
Set the URI to a folder containing CSV files: C:\folder1.
You can also connect to multiple CSV files which share the same schema. Below is an example connection string:
URI=C:\folder; AggregateFiles=True;
If you would prefer to expose all of the individual CSV files as tables instead, leave this property False.
URI=C:\folder; AggregateFiles=False;
If you need INSERT/UPDATE/DELETE cloud files, you can download the corresponding CData Sync App for that cloud host (supported via stored procedures), make changes with the local file's corresponding Sync App, then upload the file using the cloud source's stored procedures.
As an example, if you wanted to update a file stored on SharePoint, you could use the CData SharePoint Sync App's DownloadDocument procedure to download the CSV file, update the local CSV file with the CData CSV Sync App, then use the SharePoint Sync App's UploadDocument procedure to upload the changed file to SharePoint.
A unique prefix at the beginning of the URI connection property is used to identify the cloud data store being targed by the Sync App and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table).

See Connecting to SharePoint Online for more information regarding how to connect and authenticate to CSV files hosted on SharePoint Online.
You can also read from and write to system streams. Reference the stream from code with the ExtendedProperties connection property.
By default, the Sync App attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats to do so.

The following properties control how the Sync App automatically models CSV as tables when you connect:
When working with local CSV, you can also use Schema.ini files, compatible with the Microsoft Jet driver, to define columns and data types. See Using Schema.ini for a guide.
To customize column data types and other aspects of the schemas, you can save the schemas to static configuration files. The configuration files have a simple format that makes them easy to extend. For more information on extending the Sync App schemas, see Generating Schema Files.
Set the following properties to model subfolders as views:
When IncludeSubdirectories is set, the automatically detected table names follow the convention below:
| File Path | Root\subfolder1\tableA | Root\subfolder1\subfolder2\tableA |
| Table Name | subfolder1_tableA | subfolder1_subfolder2_tableA |
Specify the following to connect to data:
There are several authentication methods available for connecting to CSV including:
To authenticate using account root credentials, set these configuration parameters:
Note: Use of this authentication scheme is discouraged by Amazon for anything but simple tests. The account root credentials have the full permissions of the user, making this the least secure authentication method.
Set AuthScheme to AwsEC2Roles.
If you are using the Sync App from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. Since the Sync App automatically obtains your IAM Role credentials and authenticates with them, it is not necessary to specify AWSAccessKey and AWSSecretKey.
If you are also using an IAM role to authenticate, you must additionally specify the following:
The CSV Sync App now supports IMDSv2. Unlike IMDSv1, the new version requires an authentication token. Endpoints and response are the same in both versions.
In IMDSv2, the CSV Sync App first attempts to retrieve the IMDSv2 metadata token and then uses it to call AWS metadata endpoints. If it is unable to retrieve the token, the Sync App reverts to IMDSv1.
Set AuthScheme to AwsIAMRoles.
In many situations, it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. If you are specifying the AWSAccessKey and AWSSecretKey of an AWS root user, you may not use roles.
To authenticate as an AWS role, set these properties:
To connect to ADFS, set the AuthScheme to ADFS, and set these properties:
To authenticate to ADFS, set these SSOProperties:
Example connection string:
AuthScheme=ADFS;User=username;Password=password;SSOLoginURL='https://sts.company.com';SSOProperties='RelyingParty=https://saml.salesforce.com';
The ADFS Integrated flow indicates you are connecting with the currently logged in Windows user credentials. To use the ADFS Integrated flow, do not specify the User and Password, but otherwise follow the same steps in the ADFS guide above.
To connect to Okta, set the AuthScheme to Okta, and set these properties:
If you are using a trusted application or proxy that overrides the Okta client request OR configuring MFA, you must use combinations of SSOProperties to authenticate using Okta. Set any of the following, as applicable:
Example connection string:
AuthScheme=Okta;SSOLoginURL='https://example.okta.com/home/appType/0bg4ivz6cJRZgCz5d6/46';User=oktaUserName;Password=oktaPassword;
To connect to PingFederate, set AuthScheme to PingFederate, and set these properties:
To enable mutual SSL authentication for SSOLoginURL, the WS-Trust STS endpoint, configure these SSOProperties:
Example connection string:
authScheme=pingfederate;SSOLoginURL=https://mycustomserver.com:9033/idp/sts.wst;SSOExchangeUrl=https://us-east-1.signin.aws.amazon.com/platform/saml/acs/764ef411-xxxxxx;user=admin;password=PassValue;AWSPrincipalARN=arn:aws:iam::215338515180:saml-provider/pingFederate;AWSRoleArn=arn:aws:iam::215338515180:role/SSOTest2;
For users and roles that require multi-factor authentication, specify the following:
Note: If you want to control the duration of the temporary credentials, set the TemporaryTokenDuration property (default: 3600 seconds).
To authenticate using temporary credentials, specify the following:
The Sync App can now request resources using the same permissions provided by long-term credentials (such as IAM user credentials) for the lifespan of the temporary credentials.
To authenticate using both temporary credentials and an IAM role, set all the parameters described above, and specify these additional parameters:
You can use a credentials file to authenticate. Any configurations related to AccessKey/SecretKey authentication, temporary credentials, role authentication, or MFA can be used. To do so, set the following properties to authenticate:
This configuration requires two separate Azure AD applications:
To connect to Azure AD, set the AuthScheme to AzureAD, and set these properties:
To authenticate to Azure AD, set these SSOProperties:
Example connection string:
AuthScheme=AzureAD;OAuthClientId=3ea1c786-d527-4399-8c3b-2e3696ae4b48;OauthClientSecret=xxx;CallbackUrl=https://localhost:33333;SSOProperties='Resource=https://signin.aws.amazon.com/saml;AzureTenant=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx';
To obtain the credentials for an AzureBlob user, follow the steps below:
Set AzureStorageAccount to your Azure Blob Storage account name.
You can authenticate to Azure Blob Storage via Access Key, Shared Access Signatures (SAS), AzureAD user, Azure MSI, or Azure Service Principal.
Set the following to authenticate with an Azure Access Key:
AuthScheme must be set to AzureAD in all user account flows.
The authentication as an Azure Service Principal is handled via the OAuth Client Credentials flow. It does not involve direct user authentication. Instead, credentials are created for just the application itself. All tasks taken by the app are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.
Create an AzureAD App and an Azure Service Principal
When authenticating using an Azure Service Principal, you must create and register an Azure AD application with an Azure AD tenant. See Creating a Custom OAuth Application for more details.
In your App Registration in portal.azure.com, navigate to API Permissions and select the Microsoft Graph permissions. There are two distinct sets of permissions: Delegated permissions and Application permissions. The permissions used during client credential authentication are under Application Permissions.
Assign a role to the application
To access resources in your subscription, you must assign a role to the application.
Client Secret
Set these connection properties:
Certificate
Set these connection properties:
You are now ready to connect. Authentication with client credentials takes place automatically like any other connection, except there is no window opened prompting the user. Because there is no user context, there is no need for a browser popup. Connections take place and are handled internally.
If you are connecting from an Azure VM with permissions for Azure Data Lake Storage, set AuthScheme to AzureMSI.
If you would like to authenticate with a service principal instead of a client secret, it is also possible to authenticate with a client certificate. Set the following to authenticate:
There are two types of custom AzureAD applications: AzureAD and AzureAD with an Azure Service Principal. Both are OAuth-based.
You may choose to use your own AzureAD Application Credentials when you want to
Follow the steps below to obtain the AzureAD values for your application, the OAuthClientId and OAuthClientSecret.

Follow the steps below to obtain the AzureAD values for your application.
Use the OAuth authentication standard to connect to Box. You can authenticate with a user account or with a service account. A service account is required to grant organization-wide access scopes to the Sync App. The Sync App facilitates these authentication flows as described below.
AuthScheme must be set to OAuth in all user account flows.
Set the AuthScheme to OAuthJWT to authenticate with this method.
Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes to the Sync App.
You need to create an OAuth application in this flow. See Create a Custom OAuth App to create and authorize an app. You can then connect to Box data that the service account has permission to access.
After setting the following connection properties, you are ready to connect:
You may choose to use your own OAuth Application Credentials when you want to:
At the Box Enterprise Developer Console:
Note: Box does not back up private keys for security reasons. Be careful to back up the Public/Private JSON file. If you lose your private key, you must reset the entire keypair.
openssl genrsa -des3 -out private.pem 2048 openssl rsa -in private.pem -outform PEM -pubout -out public.pem
Note: To run OpenSSL in a Windows environment, install the Cygwin package.
After your application is created and registered, click Configuration from the main menu to access your settings. Note the displayed Redirect URI, Client ID, and Client Secret. You will need these values later.
If you change the JWT access scopes, you must reauthorize the application in the enterprise admin console:
Dropbox uses the OAuth authentication standard.
You need to choose between using CData's embedded OAuth app or Create a Custom OAuth App.
The embedded app includes the following scopes:
You may choose to use your own OAuth Application Credentials when you want to
No further values need to be specified in the CSV app settings.
Set the ProjectId property to the Id of the project you want to connect to.
The Sync App supports using user accounts and GCP instance accounts for authentication.
The following sections discuss the available authentication schemes for Google Cloud Storage:
AuthScheme must be set to OAuth in all user account flows.
Get an OAuth Access Token
Set the following connection properties to obtain the OAuthAccessToken:
Then call stored procedures to complete the OAuth exchange:
Once you have obtained the access and refresh tokens, you can connect to data and refresh the OAuth access token either automatically or manually.
Automatic Refresh of the OAuth Access Token
To have the driver automatically refresh the OAuth access token, set the following on the first data connection:
Manual Refresh of the OAuth Access Token
The only value needed to manually refresh the OAuth access token when connecting to data is the OAuth refresh token.
Use the RefreshOAuthAccessToken stored procedure to manually refresh the OAuthAccessToken after the ExpiresIn parameter value returned by GetOAuthAccessToken has elapsed, then set the following connection properties:
Then call RefreshOAuthAccessToken with OAuthRefreshToken set to the OAuth refresh token returned by GetOAuthAccessToken. After the new tokens have been retrieved, open a new connection by setting the OAuthAccessToken property to the value returned by RefreshOAuthAccessToken.
Finally, store the OAuth refresh token so that you can use it to manually refresh the OAuth access token after it has expired.
Option 1: Obtain and Exchange a Verifier Code
To obtain a verifier code, you must authenticate at the OAuth authorization URL.
Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.
On the headless machine, set the following connection properties to obtain the OAuth authentication values:
After the OAuth settings file is generated, you need to re-set the following properties to connect:
Option 2: Transfer OAuth Settings
Prior to connecting on a headless machine, you need to create and install a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.
After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.
Once you have successfully tested the connection, copy the OAuth settings file to your headless machine.
On the headless machine, set the following connection properties to connect to data:
When running on a GCP virtual machine, the Sync App can authenticate using a service account tied to the virtual machine. To use this mode, set AuthScheme to GCPInstanceAccount.
(For information on getting and setting the OAuthAccessToken and other configuration parameters, see the Desktop Authentication section of "Connecting to CSV".)
However, you must create a custom OAuth application to connect to CSV via the Web. And since custom OAuth applications seamlessly support all three commonly-used auth flows, you might want to create custom OAuth applications (use your own OAuth Application Credentials) for those auth flows anyway.
Custom OAuth applications are useful if you want to:
The following sections describe how to enable the Directory API and create custom OAuth applications for user accounts (OAuth) and Service Accounts (OAuth/JWT).
For users whose AuthScheme is OAuth and who need to authenticate over a web application, you must always create a custom OAuth application. (For desktop and headless flows, creating a custom OAuth application is optional.)
Do the following:
Note: The client secret remains accessible from from the Google Cloud Console.
To create a new service account:
To complete the service account flow, generate a private key in the Google Cloud Console. In the service account flow, the driver exchanges a JSON Web token (JWT) for the OAuthAccessToken. The private key is required to sign the JWT. The driver will have the same permissions granted to the service account.
The Sync App supports using user accounts and GCP instance accounts for authentication.
The following sections discuss the available authentication schemes for Google Drive:
AuthScheme must be set to OAuth in all user account flows.
When running on a GCP virtual machine, the Sync App can authenticate using a service account tied to the virtual machine. To use this mode, set AuthScheme to GCPInstanceAccount.

The Sync App generically supports connecting to CSV data stored on HTTP(S) streams.
Several authentication methods, such as user/password, digest access, OAuth, OAuthJWT, and OAuth PASSWORD flow are supported.
You can also connect to streams that have no authentication set up.
Connect to an HTTP(S) stream with no authentication by setting the AuthScheme connection property to None.
Set the following to connect:
Set the following to connect:
OAuth requires the authenticating user to interact with CSV using the browser. The Sync App facilitates this in various ways as described in the following sections.
Before following the procedures below, you need to register an OAuth app with the service containing the CSV data you want to work with.
Creating a custom application in most services requires registering as a developer and creating an app in the UI of the service.
This is not necessarily true for all services. In some you must contact the service provider to create the app for you. However it is done, you must obtain the values for OAuthClientId, OAuthClientSecret, and CallbackURL.
Set AuthScheme to OAuthJWT.
The Sync App supports using JWT as an authorization grant in situations where a user cannot perform an interactive sign-on. After setting the following connection properties, you are ready to connect:
Note that the JWT signature algorithm cannot be set directly. The Sync App only supports the RS256 algorithm.
The Sync App will then construct a JWT including the following fields, and submit it to OAuthAccessTokenURL for an access token.
AuthScheme: Set this to OAuthPassword.
OAuth requires the authenticating user to interact with CSV using the browser. The Sync App facilitates this in various ways as described in the following sections.

If you do not already have Cloud Object Storage in your IBM Cloud account, you can follow the procedure below to install an instance of SQL Query in your account:
To connect with IBM Cloud Object Storage, you will need an ApiKey. You can obtain this as follows:
Set Region to to your IBM instance region.
You can authenticate to IBM Cloud Object Storage using either HMAC or OAuth authentication.
Set the following properties to authenticate:
ConnectionType=IBM Object Storage Source;URI=ibmobjectstorage://bucket1/folder1; AccessKey=token1; SecretKey=secret1; Region=eu-gb;
Set the following to authenticate using OAuth authentication.
ConnectionType=IBM Object Storage Source;URI=ibmobjectstorage://bucket1/folder1; ApiKey=key1; Region=eu-gb; AuthScheme=OAuth; InitiateOAuth=GETANDREFRESH;
When you connect, the Sync App completes the OAuth process.
You can connect to OneDrive using an AzureAD user, with MSI authentication, or using an Azure Service Principal.
AuthScheme must be set to AzureAD in all user account flows.
The authentication as an Azure Service Principal is handled via the OAuth Client Credentials flow. It does not involve direct user authentication. Instead, credentials are created for just the application itself. All tasks taken by the app are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.
Create an AzureAD App and an Azure Service Principal
When authenticating using an Azure Service Principal, you must create and register an Azure AD application with an Azure AD tenant. See Creating a Custom OAuth Application for more details.
In your App Registration in portal.azure.com, navigate to API Permissions and select the Microsoft Graph permissions. There are two distinct sets of permissions: Delegated permissions and Application permissions. The permissions used during client credential authentication are under Application Permissions.

You may choose to use your own AzureAD Application Credentials when you want to
Follow the steps below to obtain the AzureAD values for your application, the OAuthClientId and OAuthClientSecret.
When authenticating using an Azure Service Principal, you must create both a custom AzureAD application and a service principal that can access the necessary resources. Follow the steps below to create a custom AzureAD application and obtain the connection properties for Azure Service Principal authentication.
Follow the steps below to obtain the AzureAD values for your application.
You can authenticate to SFTP using a user and password or an SSH certificate. Additionally, you can connect to an SFTP server that has no authentication enabled.
Set SSHAuthMode to None to connect without authentication, assuming your server supports doing so.
Provide user credentials associated with your SFTP server:

Azure AD Configuration
The main theme behind this configuration is the OAuth 2.0 On-Behalf-Of flow. It requires two Azure AD applications:
Save the step "Assign the Azure AD test user" until after provisioning so that you can select the AWS roles when assigning the user.
CData Driver Common Properties
The following SSOProperties are needed to authenticate to Azure Active Directory and must be specified for every service provider.
We will retrieve the SSO SAML response from an OAuth 2.0 On-Behalf-Of flow so the following OAuth connection properties must be specified:

Sharepoint SOAP
The following properties must be specified when connecting to a Sharepoint SOAP service provider:
AuthScheme='ADFS';User=test;Password=test;SSOProperties='Domain=test.cdata;';
Amazon S3
The following properties must be specified when connecting to a Sharepoint SOAP service provider:
AuthScheme=ADFS;User=username;Password=password;SSOLoginURL='https://sts.company.com';ADFS Integrated
The ADFS Integrated flow indicates you are connecting with the currently logged in Windows user credentials. To use the ADFS Integrated flow, simply do not specify the User and Password, but otherwise follow the same steps in the ADFS guide above.
To authenticate to CSV with Kerberos, set AuthScheme to NEGOTIATE.
Authenticating to CSV via Kerberos requires you to define authentication properties and to choose how Kerberos should retrieve authentication tickets.
The Sync App provides three ways to retrieve the required Kerberos ticket, depending on whether or not the KRB5CCNAME and/or KerberosKeytabFile variables exist in your environment.
MIT Kerberos Credential Cache File
This option enables you to use the MIT Kerberos Ticket Manager or kinit command to get tickets. With this option there is no need to set the User or Password connection properties.
This option requires that KRB5CCNAME has been created in your system.
To enable ticket retrieval via MIT Cerberos Credential Cache Files:
If the ticket is successfully obtained, the ticket information appears in Kerberos Ticket Manager and is stored in the credential cache file.
The Sync App uses the cache file to obtain the Kerberos ticket to connect to CSV.
Note: If you would prefer not to edit KRB5CCNAME, you can use the KerberosTicketCache property to set the file path manually. After this is set, the Sync App uses the specified cache file to obtain the Kerberos ticket to connect to CSV.
Keytab File
If your environment lacks the KRB5CCNAME environment variable, you can retrieve a Kerberos ticket using a Keytab File.
To use this method, set the User property to the desired username, and set the KerberosKeytabFile property to a file path pointing to the keytab file associated with the user.
User and Password
If your environment lacks the KRB5CCNAME environment variable and the KerberosKeytabFile property has not been set, you can retrieve a ticket using a user and password combination.
To use this method, set the User and Password properties to the user/password combination that you use to authenticate with CSV.
To enable this kind of cross-realm authentication, set the KerberosRealm and KerberosKDC properties to the values required for user authentication. Also, set the KerberosServiceRealm and KerberosServiceKDC properties to the values required to obtain the service ticket.
Set the following properties to control how the Sync App models CSV as tables:
The CData Sync App hides the complexity of processing local and remote CSV data, from connecting over wire protocols to modeling the data as tables. However, you also have control over these layers.
The Sync App dynamically derives schemas from CSV based on the connection properties specified. The available connection properties give you control over many aspects of how CSV data is modeled as tables. See Connecting to CSV Data Sources for more information on configuring the connection. When working with local CSV, you can also configure the column definitions and file format with Schema.ini, the configuration used by the Microsoft Jet driver.
For more granular control over the columns reported and other aspects of modeling the data as tables, you can define your own schemas or extend the generated ones. Schemas are defined in extendable configuration files. See Generating Schema Files to save the detected schemas to configuration files, which you can then easily edit.
The following sections show how to customize schemas or write your own from scratch.
Tables and views are defined by authoring schema files in API Script. API Script is a simple configuration language that allows you to define the columns and the behavior of the table. It also has built-in operations that enable you to process CSV.
In addition to these data processing primitives, API Script is a full-featured language with constructs for conditionals, looping, etc. However, as shown by the example schema, for most table definitions you will not need to use these features.
Below is a fully functional table schema that models the Person entity in the popular Northwind sample database. It contains all the components you will need to access your data source through SQL. You can find more information on using these components in Column Definitions and SELECT Execution.
<api:script>
<!-- See Column Definitions to define column behavior. -->
<api:info title="CSVPersons" desc="Parse the CSV Persons feed.">
<attr name="ID" xs:type="int" key="true" />
<attr name="EmployeeID" xs:type="int" />
<attr name="Name" xs:type="string" />
<attr name="TotalExpense" xs:type="double" />
<attr name="HireDate" xs:type="datetime" />
<attr name="Salary" xs:type="int" />
</api:info>
<api:set attr="uri" value="http://pathtocsvstream" />
<!-- The GET method corresponds to SELECT. The results of processing are pushed to the schema's output. See SELECT Execution for more information. -->
<api:script method="GET" >
<api:call op="csvproviderGet"/>
</api:script>
<!-- Not implemented -->
<api:script method="POST">
<api:call op="csvproviderInsert">
<api:push/>
</api:call>
</api:script>
<!-- Not implemented -->
<api:script method="MERGE">
<api:call op="csvproviderUpdate">
<api:push/>
</api:call>
</api:script>
<!-- Not implemented -->
<api:script method="DELETE">
<api:call op="csvproviderDelete">
<api:push/>
</api:call>
</api:script>
</api:script>
In the Schema.ini file you can specify the format of a text file you want to model as a table and you can also define the columns of the table. Schema.ini must be located in the folder specified in the URI -- or, if IncludeSubdirectories is set, Schema.ini can be defined in each subfolder.
To allow you to define a Schema.ini only when necessary, you can also use IncludeFiles and ExtendedProperties.
ExtendedProperties is compatible with Microsoft Jet OLE DB 4.0. The format for all text files can be set in ExtendedProperties. Schema.ini overrides ExtendedProperties for a specific file.
Files specified in Schema.ini are reported as tables in addition to files included by IncludeFiles. The Sync App uses a definition in Schema.ini if one exists and the filename otherwise to report the table.
A section in Schema.ini must begin with the file name enclosed in square brackets. For example:
[Jerrie's travel expense.txt]
After adding a file name entry, you can set the Format property to the format of the file. The possible values are the following:
Format=Delimited(,)Note: By default, .txt files are processed as CSV files with headers.
There are two ways to define columns based on the fields in your text files:
To define a column in Schema.ini, use the following format:
Coln=ColumnName DataType [Width Width]
For example:
Col2=A Text Width 100Note: If format is set to fixed length, then defining the width of each column is mandatory.
[Jerrie's travel expense.csv] ColNameHeader=True Format=Delimited(,) Col1=Date Text Col2=A Text Col3=B Text Col4=C Text Col5=Total Text Col6=Date Text Col7=D Text Col8=E Text Col9=F Text Col10=G Text Col11=rate numeric [invoices.csv] ColNameHeader=True Format=Delimited(,) Col1=id numeric Col2=invoicedate date Col3=total numeric
Data types can be any of the following:
The CData Sync App enables you to persist schema definitions to configuration files. Schema files make it easy to customize and save the dynamically detected schemas, or to define your own view of the data.
The following sections show how to use the GenerateSchemaFiles property to save the table definitions detected based on the connection string. Alternatively, you can invoke the CreateSchema stored procedure to manually generate a schema file based on the provided input parameters.
After creating a schema, see Modeling CSV Data for more information on extending table schemas to gain further control over data types and other aspects of modeling CSV as tables.
Set the following additional connection properties to generate table schemas for local or remote CSV:
Note: Columns defined in .rsd files take precedence over the definitions in Schema.ini. Columns defined in generated schema files take precedence over the definitions in Schema.ini.
The basic attributes of a column are the name of the column, the data type, whether the column is a primary key, and the internal name. The Sync App uses the internal name to extract nodes from CSV with no readable names.
Mark up column attributes in the api:info block of the schema file. You can set the internal name in the other:internalname property. You can also specify the format of the resulting column value with other:valueFormat.
To see the column definitions in a complete example, refer to Modeling CSV Data.
<api:info title="CSVPersons" desc="Parse the CSV Persons feed.">
<attr name="ID" xs:type="int" key="true" />
<attr name="EmployeeID" xs:type="int" other:internalname="employee_id" />
<attr name="Name" xs:type="string" />
<attr name="TotalExpense" xs:type="double" />
<attr name="HireDate" xs:type="datetime" />
<attr name="Salary" xs:type="int" />
</api:info>
The other:internalname property is used to specify the CSV column name that selects the column's value from CSV. So, if the CSV file contains a column name employee_id you use other:internalname="employee_id"
With a URI and Column Definitions specified, the Sync App processes SELECT statements client-side, in memory, through SupportEnhancedSQL. The following sections show how to use the Sync App's built-in operations to customize how the Sync App requests and returns data from the server.
When a SELECT query is issued, the Sync App executes the GET method of the schema. In this method you can process CSV. To see this schema in a complete example, refer to Modeling CSV Data.
The following line maps the schema to a URI:
<api:set attr="uri" value="ftp://somewebsite/NorthwindOData.csv" />
Invoke the operation to retrieve the data in the GET method. Specify the operation with the api:push keyword. The following lines push the results of processing to the schema's output.
<api:script method="GET" >
<api:push op="csvproviderGet"/>
</api:script>
You can then execute WHERE clause searches, JOIN queries, and SQL aggregate functions.
The Sync App's operations give you high level control over the request sent to the server. You can set a variety of inputs to control authentication and other aspects of the request. See Operations for the available inputs.
You can also build the request by injecting inputs from the SQL statement. As an example, the following sections show how to use the WHERE clause to change the request dynamically. Note that other filters specified in the WHERE clause are processed client-side by the Sync App; you can search on any column returned in the response.
Consider a weather forecast API that returns a location's forecast in CSV. You specify the location you want in the URI. Using the Sync App, you could get the forecast with a query like the following:
SELECT * FROM Forecasts WHERE (Location = '90210')
Follow the steps below to implement this query. The following procedure defines a pseudo column, an input that can only be used in the WHERE clause, and maps the pseudo column to an API request.
<api:info>
...
<input name="Location" required="true"/>
</api:info>
<api:set attr='uri' value="http://api.wunderground.com/api/MyAPIKey/hourly/q/[_input.Location].csv"/>
<api:script method="GET" >
<api:push op="csvproviderGet"/>
</api:script>To override the Sync App's internal paging mechanism, add the Rows@Next input to the list of columns in the api:info block.
<input name="rows@next" desc="Identifier for the next page of results." />
Note that making this an input parameter instead of an attr parameter will prevent it from
showing up in column listings.
You will also need to set the EnablePaging attribute to TRUE to turn off the driver's internal paging mechanism.
<api:set attr="EnablePaging" value="TRUE" />
When the Rows@Next value is set in the output, the Sync App will automatically call the method again with the Rows@Next value in the input after it is finished returning results for this page. You can use the value of this input to modify the request on the next pass to get the next page of
data. Set the Rows@Next input to any information needed to make the request for the next page of data.
For example, your API may return the next page's URL in the response. You can obtain this value by providing the XPath to the URL:
<api:set attr="elementmappath#" value="/next_page" />
<api:set attr="elementmapname#" value="rows@next" />
You can then modify the URL where the request is made, provided the value is set. The api:check element is useful for checking the existence of a required input before attempting to access its value. The Rows@Next input can be accessed as an attribute of the _input item:
<api:check attr="_input.rows@next">
<api:set attr="uri" value="[_input.rows@next]" />
<api:else>
<api:set attr="uri" value="<first page's URL>" />
</api:else>
<api:check>
You can use the _query item to access any component of the SELECT statement in the schema.
| query | The SQL query. For example:
SELECT Id, Name FROM Accounts WHERE City LIKE '%New%' AND COUNTRY = 'US' GROUP BY CreatedDate ORDER BY Name LIMIT 10,50; |
| selectcolumns | A comma-separated list containing the columns specified in the SELECT statement. For example, the Id and Name columns in the example. |
| table | The table name specified in the SELECT statement. For example, Accounts in the example. |
| criteria | The WHERE clause of the statement. For example, the following WHERE clause in the example:
City LIKE '%New%' AND COUNTRY = 'US' |
| orderby | The columns specified in the ORDER BY clause. For example, Name in the example. |
| groupby | The GROUP BY clause in the SELECT statement. For example, CreatedDate in the example. |
| limit | The limit specified in the LIMIT or TOP clauses of the SELECT statement. For example, 50 in the example. |
| offset | The offset specified in the LIMIT or TOP clauses of the SELECT statement. For example, 10 in the example. |
| isjoin | Whether the query is a join. |
| jointable | The table to be joined. |
| isschemaonly | Whether the query retrieves only schema information. |
The Sync App has high-performance, built-in operations for accessing data from CSV data sources. These operations are platform neutral: Schema files that invoke these operations can be used in both .NET and Java. You can also extend the Sync App with your own operations written in .NET or Java.
The Sync App consists of the following operations:
| Operation Name | Description | |
| csvproviderGet | The csvproviderGet operation is an API Script operation that is used to process CSV content. It allows you to split CSV content into rows. | |
| oauthGetAccessToken | For OAuth 1.0, exchange a request token for an access token. For OAuth 2.0, get an access token or get a new access token with the refresh token. | |
| oauthGetUserAuthorizationURL | Generates the user authorization URL. OAuth 2.0 will not access the network in this operation. |
The csvproviderGet operation is an API Script operation that is used to process CSV content. It allows you to split CSV content into rows.
The csvproviderGet operation can be used to execute remote data retrieval operations. It abstracts the request and also enables configuration of most aspects through the following inputs, including authentication and firewall traversal. See ProxyAuthScheme and FirewallType the properties needed to negotiate a firewall.
The csvproviderGet operation reads the api:info section of the table schema file to map various elements in the CSV document into column values within a row. It does so using the other:internalname property of the column definition.
The oauthGetAccessToken operation is an API Script operation that is used to facilitate the OAuth authentication flow. To pass the needed inputs to the operation, define the GetOAuthAccessToken stored procedure and, if your data source has a refresh flow, RefreshOAuthAccessToken. The Sync App can call this internally.
The Sync App includes stored procedures that invoke this operation to complete the OAuth exchange. The following example schema briefly lists some of the typically required inputs before the following sections explain them in more detail.
For a guide to using the Sync App to authenticate, see the "Getting Started" chapter.
Invoke the oauthGetAccessToken with the GetOAuthAccessToken stored procedure. The following inputs are required for most data sources and will provide default values for the connection properties of the same name.
<api:script xmlns:api="http://www.rssbus.com/ns/rsbscript/2">
<api:info title="GetOAuthAccessToken" description="Obtains the OAuth access token to be used for authentication with various APIs." >

<api:set attr="OAuthRequestTokenURL" value="http://MyOAuthRequestTokenURL" />
<!-- Set OAuthAuthorizationURL to the URL where the user logs into the service and grants permissions to the application. -->
<api:set attr="OAuthAuthorizationURL" value="http://MyOAuthAuthorizationURL" />
<!-- Set OAuthAccessTokenURL to the URL where the request for the access token is made. -->
<api:set attr="OAuthAccessTokenURL" value="http://MyOAuthAccessTokenURL" />
<!-- Set GrantType to the authorization grant type. OAuth 2.0 only. -->
<api:set attr="GrantType" value="CODE" />

<api:set attr="SignMethod" value="HMAC-SHA1" />
<api:call op="oauthGetAccessToken">
<api:push/>
</api:call>
</api:script>
You can also use oauthGetAccessToken to refresh the access token by providing the following inputs:
<api:script xmlns:api="http://www.rssbus.com/ns/rsbscript/2">
<api:info title="RefreshOAuthAccessToken" description="Refreshes the OAuth access token used for authentication." >
<input name="OAuthRefreshToken" desc="A token that may be used to obtain a new access token." />

<output name="OAuthRefreshToken" desc="A token that may be used to obtain a new access token." />
<output name="ExpiresIn" desc="The remaining lifetime on the access token." />
</api:info>
<!-- Set OAuthVersion to 1.0 or 2.0. -->
<api:set attr="OAuthVersion" value="MyOAuthVersion" />
<!-- Set GrantType to REFRESH. OAuth 2.0 only. -->
<api:set attr="GrantType" value="REFRESH" />
<!-- Set SignMethod to the signature method used to calculate the signature of the request. OAuth 1.0 only.-->
<api:set attr="SignMethod" value="HMAC-SHA1" />
<!-- Set OAuthAccessTokenURL to the URL where the request for the access token is made. -->
<api:set attr="OAuthAccessTokenURL" value="http://MyOAuthAccessTokenURL" />
<!-- Set AuthMode to 'WEB' when calling RefreshOAuthAccessToken -->
<api:set attr="AuthMode" value="WEB"/>
<api:call op="oauthGetAccessToken">
<api:push/>
</api:call>
</api:script>
The oauthGetUserAuthorizationURL is an API Script operation that is used to facilitate the OAuth authentication flow for Web apps, for offline apps, and in situations where the Sync App is not allowed to open a Web browser. To pass the needed inputs to this operation, define the GetOAuthAuthorizationURL stored procedure. The Sync App can call this internally.
Define stored procedures in .rsb files with the same file name as the schema's title. The example schema briefly lists some of the typically required inputs before the following sections explain them in more detail.
For a guide to authenticating in the OAuth flow, see the "Getting Started" chapter.
Call oauthGetUserAuthorizationURL in the GetOAuthAuthorizationURL stored procedure.

This section details a selection of advanced features of the CSV Sync App.
The Sync App allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.
Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.
Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.
The Sync App offloads as much of the SELECT statement processing as possible to CSV and then processes the rest of the query in memory (client-side).
See Query Processing for more information.
See Logging for an overview of configuration settings that can be used to refine CData logging. For basic logging, you only need to set two connection properties, but there are numerous features that support more refined logging, where you can select subsets of information to be logged using the LogModules connection property.
By default, the Sync App attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.
To specify another certificate, see the SSLServerCert property for the available formats to do so.
The CSV Sync App also supports setting client certificates. Set the following to connect using a client certificate.
To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.
In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.
Set the following properties:

Your AWS account secret key. This value is accessible from your AWS security credentials page.
Your AWS account secret key. This value is accessible from your AWS security credentials page:
The Amazon Resource Name of the role to use when authenticating.
When authenticating outside of AWS, it is common to use a Role for authentication instead of your direct AWS account credentials. Entering the AWSRoleARN will cause the CData Sync App to perform a role based authentication instead of using the AWSAccessKey and AWSSecretKey directly. The AWSAccessKey and AWSSecretKey must still be specified to perform this authentication. You cannot use the credentials of an AWS root user when setting RoleARN. The AWSAccessKey and AWSSecretKey must be those of an IAM user.
The ARN of the SAML Identity provider in your AWS account.
The ARN of the SAML Identity provider in your AWS account.
The hosting region for your Amazon Web Services.
The hosting region for your Amazon Web Services. Available values are OHIO, NORTHERNVIRGINIA, NORTHERNCALIFORNIA, OREGON, CAPETOWN, HONGKONG, JAKARTA, MUMBAI, OSAKA, SEOUL, SINGAPORE, SYDNEY, TOKYO, CENTRAL, BEIJING, NINGXIA, FRANKFURT, IRELAND, LONDON, MILAN, PARIS, STOCKHOLM, ZURICH, BAHRAIN, UAE, SAOPAULO, GOVCLOUDEAST, and GOVCLOUDWEST.

Your AWS session token.
Your AWS session token. This value can be retrieved in different ways. See this link for more info.
A unique identifier that might be required when you assume a role in another account.
A unique identifier that might be required when you assume a role in another account.
The serial number of the MFA device if one is being used.
You can find the device for an IAM user by going to the AWS Management Console and viewing the user's security credentials. For virtual devices, this is actually an Amazon Resource Name (such as arn:aws:iam::123456789012:mfa/user).
The temporary token available from your MFA device.
If MFA is required, this value will be used along with the MFASerialNumber to retrieve temporary credentials to login. The temporary credentials available from AWS will only last up to 1 hour by default (see TemporaryTokenDuration). Once the time is up, the connection must be updated to specify a new MFA token so that new credentials may be obtained. %AWSpSecurityToken; %AWSpTemporaryTokenDuration;
The amount of time (in seconds) a temporary token will last.
Temporary tokens are used with both MFA and Role based authentication. Temporary tokens will eventually time out, at which time a new temporary token must be obtained. For situations where MFA is not used, this is not a big deal. The CData Sync App will internally request a new temporary token once the temporary token has expired.
However, for MFA required connection, a new MFAToken must be specified in the connection to retrieve a new temporary token. This is a more intrusive issue since it requires an update to the connection by the user. The maximum and minimum that can be specified will depend largely on the connection being used.
For Role based authentication, the minimum duration is 900 seconds (15 minutes) while the maximum if 3600 (1 hour). Even if MFA is used with role based authentication, 3600 is still the maximum.
For MFA authentication by itself (using an IAM User or root user), the minimum is 900 seconds (15 minutes), the maximum is 129600 (36 hours).
When activated, file uploads into Amazon S3 buckets will be server-side encrypted.
Server-side encryption is the encryption of data at its destination by the application or service that receives it. Amazon S3 encrypts your data at the object level as it writes it to disks in its data centers and decrypts it for you when you access it. Learn more: https://docs.aws.amazon.com/AmazonS3/latest/userguide/serv-side-encryption.html
A BASE64-encoded UTF-8 string holding JSON which represents a string-string (key-value) map.
Example of what the JSON may look decoded: {"aws:s3:arn": "arn:aws:s3:::_bucket_/_object_"}.
Configuration to use an S3 Bucket Key at the object level when encrypting data with AWS KMS. Enabling this will reduce the cost of server-side encryption by lowering calls to AWS KMS.

This section provides a complete list of the Azure Authentication properties you can configure in the connection string for this provider.
| Property | Description |
| AzureStorageAccount | The name of your Azure storage account. |
| AzureAccessKey | The storage key associated with your Azure account. |
| AzureSharedAccessSignature | A shared access key signature that may be used for authentication. |
| AzureTenant | The Microsoft Online tenant being used to access data. If not specified, your default tenant is used. |
| AzureEnvironment | The Azure Environment to use when establishing a connection. |
The name of your Azure storage account.
The name of your Azure storage account.
The storage key associated with your Azure account.
The storage key associated with your CSV account. You can retrieve it as follows:
The Microsoft Online tenant being used to access data. If not specified, your default tenant is used.
The Microsoft Online tenant being used to access data. For instance, contoso.onmicrosoft.com. Alternatively, specify the tenant Id. This value is the directory Id in the Azure Portal > Azure Active Directory > Properties.
Typically it is not necessary to specify the Tenant. This can be automatically determined by Microsoft when using the OAuthGrantType set to CODE (default). However, it may fail in the case that the user belongs to multiple tenants. For instance, if an Admin of domain A invites a user of domain B to be a guest user. The user will now belong to both tenants. It is a good practice to specify the Tenant, although in general things should normally work without having to specify it.
The AzureTenant is required when setting OAuthGrantType to CLIENT. When using client credentials, there is no user context. The credentials are taken from the context of the app itself. While Microsoft still allows client credentials to be obtained without specifying which Tenant, it has a much lower probability of picking the specific tenant you want to work with. For this reason, we require AzureTenant to be explicitly stated for all client credentials connections to ensure you get credentials that are applicable for the domain you intend to connect to.
The Azure Environment to use when establishing a connection.
In most cases, leaving the environment set to global will work. However, if your Azure Account has been added to a different environment, the AzureEnvironment may be used to specify which environment. The available values are GLOBAL, CHINA, USGOVT, USGOVTDOD.

The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is "%APPDATA%\\CData\\CSV Data Provider\\Schema" with %APPDATA% being set to the user's configuration directory:
| Platform | %APPDATA% |
| Windows | The value of the APPDATA environment variable |
| Linux | ~/.config |
This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.
This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.
Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the Sync App.
This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.
Specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.
Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.
Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.
Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the Sync App.
This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.
Specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.
Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.
A path to the directory that contains the schema.ini file.
A path to the directory that contains the schema.ini file. Might additionally be used to specify a different name for the schema.ini file.
When set to true, the provider will aggregate all the files located in the URI directory that have the same schema into a single table called AggregatedFiles .
By default, the first file in the folder is used to define the schema, however MetadataDiscoveryURI can be specified to use a different file instead.
Take for example the following CSV contents.
File 1
ItemID,Name,NumInStock 1,Peanuts - Salted,76 2,Peanuts - Unsalted,43 3,Raisins,26
File 2
ItemID,Name,NumInStock 4,Pretzels - Original,55 5,Pretzels - Chocolate,35 6,Toffee,44
The resulting aggregate table is shown below. Note that only the columns present in the defined schema are used in the aggregate.
AggregateFiles
ItemID,Name,NumInStock 1,Peanuts - Salted,76 2,Peanuts - Unsalted,43 3,Raisins,26 4,Pretzels - Original,55 5,Pretzels - Chocolate,35 6,Toffee,44
Used together with AggregateFiles , this property specifies a specific file to read the schema of the AggregatedFiles result set.
Used together with AggregateFiles, this property specifies a specific file to read the schema of the AggregatedFiles result set.
Determines how to determine the data types of columns.
| None | Setting TypeDetectionScheme to None will return all columns as the string type. |
| RowScan | Setting TypeDetectionScheme to RowScan will scan rows to heuristically determine the data type. The RowScanDepth determines the number of rows to be scanned. |
| ColumnCount | Setting TypeDetectionScheme to ColumnCount will control the number for columns to detect and will return all columns as the string type. The ColumnCount property determines the number of columns. |
The number of columns to detect when dynamically determining columns for the table.
The number of columns to detect when dynamically determining columns for the table. Columns are dynamically determined when a schema (RSD) file is not available for the table, such as when using GenerateSchemaFiles. To specify the number of columns set the ColumnCount connection property.
The number of rows to scan when dynamically determining columns for the table.
The number of rows to scan when dynamically determining columns for the table. Columns are dynamically determined when a schema (RSD) file is not available for the table, such as when using GenerateSchemaFiles.
Higher values will result in a longer request, but will be more accurate.
Setting this value to 0 (zero) will parse the entire CSV document.
This section provides a complete list of the Data Formatting properties you can configure in the connection string for this provider.
| Property | Description |
| IncludeColumnHeaders | Whether to get column names from the first line of the specified files. |
| FMT | The format to be used to parse all text files. |
| ExtendedProperties | The Microsoft Jet OLE DB 4.0-compatible extended properties for text files. |
| RowDelimiter | The character that will be used to detect the end of a CSV row. |
| SkipTop | Skips the amount of rows specified starting from the top. |
| IgnoreBlankRows | Indicates whether to skip the empty rows. |
| IncludeEmptyHeaders | Whether to include empty value for a column name within column header. |
| SkipHeaderComments | If set to true, skips rows at the top of the file beginning with #. |
| Charset | Specifies the session character set for encoding and decoding character data transferred to and from the CSV file. The default value is UTF-8. |
| QuoteEscapeCharacter | Determines the character which will be used to escape quotes. |
| QuoteCharacter | Determines the character which will be used to quote values in CSV file. |
| TrimSpaces | Set to True if you want the provider to trim preceeding and trailing spaces in a cell containing a quoted value. |
| PushEmptyValuesAsNull | Indicates whether to read the empty values as empty or as null. |
| NullValues | A comma separated list which will be replaced with nulls if there are found in the CSV file. |
| PathSeparator | Determines the character which will be used to replace the file separator. |
| IgnoreIncompleteRows | Indicates whether to ignore incomplete rows. |
| MaxCellLength | Max length a cell can hold, after passing this number the cell content will get truncated. If value is -1 then we don't limit the cell content length. |
| DateTimeFormat | This setting specifies in which format the datetime values will be written to for CSV files. |
Whether to get column names from the first line of the specified files.
When this property is set to True, the Sync App will derive column names for each table from the first row of each file. When this property is set to False, column names are simply the column numbers; that is, if column names have not been defined in Schema.ini.
As with Microsoft Jet OLE DB 4.0, this property can also be specified in ExtendedProperties. The IncludeColumnHeaders value specified in ExtendedProperties overrides this property.
The following connection string parses .csv and .log files as CSV without headers:
DataSource=C:\mycsvlogs;IncludeColumnHeaders=False;Include Files='CSV,LOG'
The format to be used to parse all text files.
When this connection property is set, the Sync App will parse all text files in the URI according to the specified file format. The text file format can also be specified in ExtendedProperties, as with the Microsoft Jet OLE DB 4.0 ExtendedProperties for text files. The format specified in ExtendedProperties overrides the format set as a stand-alone connection property. The Format property in Schema.ini overrides the file format set in the connection string.
The FMT can be set to one of the following values:
The following connection string parses all text files in the folder specified in the URI as tab-delimited values with headers:
URI=C:\mytsv;FMT=TabDelimited
If the property is set to anything other than the values specified above, the literal character of the specified input will be read as the delimiter, for example:
URI=C:\mypipdelimitedfile;FMT=||
This property supports hexadecimal delimiters. The Sync App treats any value starting with '0x' (Ex: FMT=0x01) as a hexadecimal, as opposed to a string literal, delimiter.
Note that hexadecimal delimiters have no escape mechanism.
The Microsoft Jet OLE DB 4.0-compatible extended properties for text files.
The Microsoft Jet OLE DB 4.0-compatible extended properties for text files. You can specify the format of text files in this property. When processing local files, the format specified for an individual file in Schema.ini overrides the format specified in ExtendedProperties.
The following example can be used to parse all text files in the URI folder as tab-delimited values with headers: ExtendedProperties='text;FMT=TabDelimited'.
Parse .csv and .log files as CSV without headers:
ExtendedProperties='text;IncludeColumnHeaders=False';Include Files='CSV,LOG'To make the connection string -- which is itself delimited -- easier to read, you can specify IncludeColumnHeaders and FMT. These stand-alone properties are overriden by ExtendedProperties.
The character that will be used to detect the end of a CSV row.
It is not necessary to specify this property if your CSV file has \r, \n, \r\n, \n\r as row delimiters.
This property supports hexadecimal delimiters. The Sync App treats any value starting with '0x' (Ex: RowDelimiter=0x01) as a hexadecimal, as opposed to a string literal, delimiter.
Note that hexadecimal delimiters have no escape mechanism.
Skips the amount of rows specified starting from the top.
Skips the amount of rows specified starting from the top.
Indicates whether to skip the empty rows.
Indicates whether to skip the empty rows.
Whether to include empty value for a column name within column header.
When this property is set to False, the Sync App will not include columns which do not have a value within column header. When set to True, the Sync App will derive column names from the column numbers. This will be only for columns without header value. If a column has a header value, it will remain the same.
If set to true, skips rows at the top of the file beginning with #.
This will skip rows starting with # until a row is found that does not start with #. Subsequent rows will be read regardless of whether they begin with #.
Specifies the session character set for encoding and decoding character data transferred to and from the CSV file. The default value is UTF-8.
Specifies the session character set for encoding and decoding character data transferred to and from the CSV file. The default value is UTF-8.
Determines the character which will be used to escape quotes.
Determines the character which will be used to escape quotes.
Determines the character which will be used to quote values in CSV file.
Determines the character which will be used to quote values in CSV file.
Note: This property works only for CSV files. Set this property to "NONE" if you want to insert fields in a CSV file without quoting them.
Set to True if you want the provider to trim preceeding and trailing spaces in a cell containing a quoted value.
Set to True if you want the provider to trim preceeding and trailing spaces in a cell containing a quoted value. If set to False and the first character in a cell is not the quote character, the cell will be treated as a literal unquoted value.
Indicates whether to read the empty values as empty or as null.
Indicates whether to read the empty values as empty or as null.
A comma separated list which will be replaced with nulls if there are found in the CSV file.
A comma separated list which will be replaced with nulls if there are found in the CSV file. Example: "NaN,\N,N/A". If any of the specified values is found in a CSV row, it will be pushed as null.
Determines the character which will be used to replace the file separator.
Determines the character which will be used to replace the file separator. If there is a CSV file located in "Test/CSVFiles/Test.csv" and if this property is set to "_", then the table name for this file would be "Test_CSVFiles_Test.csv".
Indicates whether to ignore incomplete rows.
Indicates whether to ignore the rows that do not match the headers.
Max length a cell can hold, after passing this number the cell content will get truncated. If value is -1 then we don't limit the cell content length.
Max length a cell can hold, after passing this number the cell content will get truncated. If value is -1 then we don't limit the cell content length.
This setting specifies in which format the datetime values will be written to for CSV files.
The format should follow a specified pattern:
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| BatchNamingConvention | Determines the naming convention of batch files. |
| ClientCulture | This property can be used to specify the format of data (e.g., currency values) that is accepted by the client application. This property can be used when the client application does not support the machine's culture settings. For example, Microsoft Access requires 'en-US'. |
| CreateBatchFolder | Whether to create a folder when InsertMode is set to FilePerBatch. |
| Culture | This setting can be used to specify culture settings that determine how the provider interprets certain data types that are passed into the provider. For example, setting Culture='de-DE' will output German formats even on an American machine. |

| InsertMode | Specifies the mode for inserting data into CSV files. |
| MaxRows | Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses. |
| Other | These hidden properties are used only in specific use cases. |
| Pagesize | The maximum number of results to return per page from CSV. |
| PseudoColumns | This property indicates whether or not to include pseudo columns as columns to the table. |
| Timeout | The value in seconds until the timeout error is thrown, canceling the operation. |
| TruncateOnInserts | Set to True if you want the provider to truncate on every (batch) INSERT. |
| UserDefinedViews | A filepath pointing to the JSON configuration file containing your custom views. |
| UseRowNumbers | Set this to true if you are deleting or updating in CSV and you do not want to specify a custom schema. This will create a new column with the name RowNumber which will be used as key for that table. |
Determines the naming convention of batch files.
Determines the naming convention of batch files.
This property can be used to specify the format of data (e.g., currency values) that is accepted by the client application. This property can be used when the client application does not support the machine's culture settings. For example, Microsoft Access requires 'en-US'.
This option affects the format of Sync App output. To specify the format that defines how input should be interpreted, use the Culture option. By default the Sync App uses the current locale settings of the machine to interpret input and format output.
Whether to create a folder when InsertMode is set to FilePerBatch.
Whether to create a folder when InsertMode is set to FilePerBatch.
This setting can be used to specify culture settings that determine how the provider interprets certain data types that are passed into the provider. For example, setting Culture='de-DE' will output German formats even on an American machine.
This property affects the Sync App input. To interpret values in a different cultural format, use the Client Culture property. By default the Sync App uses the current locale settings of the machine to interpret input and format output.
Other headers as determined by the user (optional).
This property can be set to a string of headers to be appended to the HTTP request headers created from other properties, like ContentType, From, and so on.
The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by the carriage return and line feed (CRLF) characters.
Use this property with caution. If this property contains invalid headers, HTTP requests may fail.
This property is useful for fine-tuning the functionality of the Sync App to integrate with specialized or nonstandard APIs.
The custom query string to be included in the request.
The CustomUrlParams allow you to specify custom query string parameters that are included with the HTTP request. The parameters must be encoded as a query string in the form field1=value1&field2=value2&field3=value3. The values in the query string must be URL encoded.
Limit the subfolders recursively scanned when IncludeSubdirectories is enabled.
When IncludeSubdirectories is enabled, DirectoryRetrievalDepth specifies how many subfolders will be recursively scanned before stopping. -1 specifies that all subfolders are scanned.
Set to true if file extensions should be excluded from table names.
Set to true if file extensions should be excluded from table names. For example, if set to True, this will make table `users.csv` appear as `users`.
Comma-separated list of file extensions to exclude from the set of the files modeled as tables.
It is also possible to specify datetime filters. We currently support CreatedDate and ModifiedDate. All extension filters are evaluated in disjunction (using OR operator), and then the resulting filter is evaluated in conjunction (using AND operator) with the datetime filters.
Examples:
ExcludeFiles="TXT,CreatedDate<='2020-11-26T07:39:34-05:00'"
ExcludeFiles="TXT,ModifiedDate<=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 50, 000)"
ExcludeFiles="ModifiedDate>=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 49, 000),ModifiedDate<=CURRENT_TIMESTAMP()"
The ID of a folder in Google Drive. If set, the resource location specified by the URI is relative to the Folder ID for all operations.
The ID of a folder in Google Drive. If set, the resource location specified by the URI is relative to the Folder ID for all operations.
Indicates the user preference as to when schemas should be generated and saved.
This property outputs schemas to .rsd files in the path specified by Location.
Available settings are the following:
Columns defined in .rsd files take precedence over the definitions in Schema.ini. Note that if you want to regenerate a file, you will first need to delete it.
When you set GenerateSchemaFiles to OnUse, the Sync App generates schemas as you execute SELECT queries. Schemas are generated for each table referenced in the query.
When you set GenerateSchemaFiles to OnCreate, schemas are only generated when a CREATE TABLE query is executed.
Another way to use this property is to obtain schemas for every table in your database when you connect. To do so, set GenerateSchemaFiles to OnStart and connect.
Indicates if you want to include Dropbox team files and folders.
In order to access Dropbox team folders and files, please set this connection property to True.
Comma-separated list of file extensions to include into the set of the files modeled as tables.
Comma-separated list of file extensions to include into the set of the files modeled as tables. For example, IncludeFiles=TXT,TAB. The default is CSV, TAB, and TXT.
A 'NOEXT' value can be specified to include files without an extension.
The following archive types are also supported (only when AggregateFiles is true): ZIP, TAR, and GZ. Files of these types are modeled as an aggregated table. You can use DirectoryRetrievalDepth and IncludeSubdirectories to refine the subset of files in the archive that are included in the aggregate table.
When archive files are found, they will be downloaded to the local machine so the Sync App can extract and parse the contained files. Note: Files contained within an archive must match an extension listed in IncludeFiles to be included in the set of files modeled as tables.
File masks can be specified using an asterisk (*) to provide enhanced filtering capabilities; e.g. IncludeFiles=2020*.csv,TXT.
Files specified in Schema.ini are honored in addition to the files included by this property.
It is also possible to specify datetime filters. We currently support CreatedDate and ModifiedDate. All extension filters are evaluated in disjunction (using OR operator), and then the resulting filter is evaluated in conjunction (using AND operator) with the datetime filters.
Examples:
IncludeFiles="TXT,CreatedDate<='2020-11-26T07:39:34-05:00'"
IncludeFiles="TXT,ModifiedDate<=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 50, 000)"
IncludeFiles="ModifiedDate>=DATETIMEFROMPARTS(2020, 11, 26, 7, 40, 49, 000),ModifiedDate<=CURRENT_TIMESTAMP()"
Whether Google Drive shared drive items should be included in results. If not present or set to false, then shared drive items are not returned.
If this property is set to 'True', files will be retrieved from all drives, including shared drives. The file retrieval can be limited a specific shared drive or a specific folder in that shared drive by setting the start of the URI to the path of the shared drive and optionally any folder within, for example: 'gdrive://SharedDriveA/FolderA/...'. Additionally, the FolderId property can be used to limit the search to an exact subdirectory.
Whether to read files from nested folders. In the case of a name collision, table names are prefixed by the underscore-separated folder names.
Whether to read files from nested folders. When accessing local CSV, the Sync App honors Schema.ini defined in subfolders. Table names are prefixed by each nested folder name separated by underscores only in the case of a table name conflict. For example,
| Root\subfolder1\tableA | Root\subfolder1\subfolder2\tableA |
| subfolder1_tableA | subfolder1_subfolder2_tableA |
Archive files (ZIP, GZ, TAR) are also supported and treated like folders.
Specifies the mode for inserting data into CSV files.
There are two modes available for inserting data to CSV file:
Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
These hidden properties are used only in specific use cases.
The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.
Specify multiple properties in a semicolon-separated list.
| DefaultColumnSize | Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000. |
| ConvertDateTimeToGMT | Determines whether to convert date-time values to GMT, instead of the local time of the machine. |
| RecordToFile=filename | Records the underlying socket data transfer to the specified file. |
The maximum number of results to return per page from CSV.
The Pagesize property affects the maximum number of results to return per page from CSV. Setting a higher value may result in better performance at the cost of additional memory allocated per page consumed.
This property indicates whether or not to include pseudo columns as columns to the table.
This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudo column unless it is a table column. The value of this connection setting is of the format "Table1=Column1, Table1=Column2, Table2=Column3". You can use the "*" character to include all tables and all columns; for example, "*=*".
The value in seconds until the timeout error is thrown, canceling the operation.
If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.
If Timeout expires and the operation is not yet complete, the Sync App throws an exception.
Set to True if you want the provider to truncate on every (batch) INSERT.
Set to True if you want the provider to truncate on every (batch) INSERT.
A filepath pointing to the JSON configuration file containing your custom views.
User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The Sync App automatically detects the views specified in this file.
You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the Sync App.
This User Defined View configuration file is formatted as follows:
For example:
{
"MyView": {
"query": "SELECT * FROM NorthwindOData WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:
"UserDefinedViews", C:\Users\yourusername\Desktop\tmp\UserDefinedViews.jsonNote that the specified path is not embedded in quotation marks.
Set this to true if you are deleting or updating in CSV and you do not want to specify a custom schema. This will create a new column with the name RowNumber which will be used as key for that table.
Set this to true if you are deleting or updating in CSV and you do not want to specify a custom schema. This will create a new column with the name RowNumber which will be used as key for that table.
