The CData Sync App provides a straightforward way to continuously pipeline your SAP HANA XSA data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.
The SAP HANA XSA connector can be used from the CData Sync application to pull data from SAP HANA XSA and move it to any of the supported destinations.
The Sync App leverages the SAP HANA XSA API to enable bidirectional access to SAP HANA XSA.
For required properties, see the Settings tab.
For connection properties that are not typically required, see the Advanced tab.
SAP HANA XSA uses the OAuth authentication standard. Before connecting, it is necessary to establish an SAP HANA XSA OData Service. See Creating a Custom OAuth App for a guide.
To connect to SAP HANA XSA using the OAuthPassword Grant type set the following:
Once you've configured the OData Service, you can establish a connection using Custom Credentials.
This section details a selection of advanced features of the SAP HANA XSA Sync App.
The Sync App supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views .
Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats;. For further information, see the SSLServerCert property under "Connection String Options" .
Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.
For further information, see Query Processing.
By default, the Sync App attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.
To specify another certificate, see the SSLServerCert connection property.
To authenticate to an HTTP proxy, set the following:
Set the following properties:
This section shows the available API objects and provides more information on executing SQL to SAP HANA XSA APIs.
The Sync App dynamically obtains table metadata from the SAP HANA XSA OData service. See Metadata Discovery for more information.
The Sync App dynamically obtains read-only view metadata from the SAP HANA XSA OData service. See Metadata Discovery for more information.
Stored Procedures are function-like interfaces to SAP HANA XSA. Stored procedures allow you to execute operations to SAP HANA XSA, including downloading documents and moving envelopes.

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.
| Property | Description |
| FirewallType | Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall. |
| FirewallServer | Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources. |
| FirewallPort | Specifies the TCP port to be used for a proxy-based firewall. |
| FirewallUser | Identifies the user ID of the account authenticating to a proxy-based firewall. |
| FirewallPassword | Specifies the password of the user account authenticating to a proxy-based firewall. |
Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.
Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.
Note: By default, the Sync App connects to the system proxy. To disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.
The following table provides port number information for each of the supported protocols.
| Protocol | Default Port | Description |
| TUNNEL | 80 | The port where the Sync App opens a connection to SAP HANA XSA. Traffic flows back and forth via the proxy at this location. |
| SOCKS4 | 1080 | The port where the Sync App opens a connection to SAP HANA XSA. SOCKS 4 then passes theFirewallUser value to the proxy, which determines whether the connection request should be granted. |
| SOCKS5 | 1080 | The port where the Sync App sends data to SAP HANA XSA. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes. |
To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.

| ProxySSLType | The SSL type to use when connecting to the proxy server specified in the ProxyServer connection property. |
| ProxyExceptions | A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property. |
Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.
When this connection property is set to True, the Sync App checks your system proxy settings for existing proxy server configurations (no need to manually supply proxy server details).
This connection property takes precedence over other proxy settings. Set to False if you want to manually configure the Sync App to connect to a specific proxy server.
To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.
The hostname or IP address of the proxy server that you want to route HTTP traffic through.
The Sync App only routes HTTP traffic through the proxy server specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server specified in your system proxy settings.
The TCP port on your specified proxy server (set in the ProxyServer connection property) that has been reserved for routing HTTP traffic to and from the client.
The Sync App only routes HTTP traffic through the proxy server port specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server port specified in your system proxy settings.
For other proxy types, see FirewallType.
Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.
The authentication type can be one of the following:
For all values other than "NONE", you must also set the ProxyUser and ProxyPassword connection properties.
If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.
The username of a user account registered with the proxy server specified in the ProxyServer connection property.
The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.
After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:
| ProxyAuthScheme Value | Value to set for ProxyUser |
| BASIC | The user name of a user registered with the proxy server. |
| DIGEST | The user name of a user registered with the proxy server. |
| NEGOTIATE | The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user. |
| NTLM | The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user. |
| NONE | Do not set the ProxyPassword connection property. |
The Sync App only uses this username if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the username specified in your system proxy settings.
The password associated with the user specified in the ProxyUser connection property.
The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.
After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:

| BASIC | The password associated with the proxy server user specified in ProxyUser. |
| DIGEST | The password associated with the proxy server user specified in ProxyUser. |
| NEGOTIATE | The password associated with the Windows user account specified in ProxyUser. |
| NTLM | The password associated with the Windows user account specified in ProxyUser. |
| NONE | Do not set the ProxyPassword connection property. |
For SOCKS 5 authentication or tunneling, see FirewallType.
The Sync App only uses this password if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the password specified in your system proxy settings.
The SSL type to use when connecting to the proxy server specified in the ProxyServer connection property.
This property determines when to use SSL for the connection to the HTTP proxy specified by ProxyServer. You can set this connection property to the following values :
| AUTO | Default setting. If ProxyServer is set to an HTTPS URL, the Sync App uses the TUNNEL option. If ProxyServer is set to an HTTP URL, the component uses the NEVER option. |
| ALWAYS | The connection is always SSL enabled. |
| NEVER | The connection is not SSL enabled. |
| TUNNEL | The connection is made through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy. |
A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property.
The ProxyServer is used for all addresses, except for addresses defined in this property. Use semicolons to separate entries.
Note that the Sync App uses the system proxy settings by default, without further configuration needed. If you want to explicitly configure proxy exceptions for this connection, set ProxyAutoDetect to False.
This section provides a complete list of the Logging properties you can configure in the connection string for this provider.
| Property | Description |
| LogModules | Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged. |
Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.
This property lets you customize the log file content by specifying the logging modules to include. Logging modules categorize logged information into distinct areas, such as query execution, metadata, or SSL communication. Each module is represented by a four-character code, with some requiring a trailing space for three-letter names.
For example, EXEC logs query execution, and INFO logs general provider messages. To include multiple modules, separate their names with semicolons as follows: INFO;EXEC;SSL.
The Verbosity connection property takes precedence over the module-based filtering specified by this property. Only log entries that meet the verbosity level and belong to the specified modules are logged. Leave this property blank to include all available modules in the log file.
For a complete list of available modules and detailed guidance on configuring logging, refer to the Advanced Logging section in Logging.
This section provides a complete list of the Schema properties you can configure in the connection string for this provider.
| Property | Description |
| Location | Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path. |
| BrowsableSchemas | Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC . |
| Tables | Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC . |
| Views | Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC . |
Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is %APPDATA%\\CData\\SAPHanaXSA Data Provider\\Schema, where %APPDATA% is set to the user's configuration directory:
| Platform | %APPDATA% |
| Windows | The value of the APPDATA environment variable |
| Linux | ~/.config |
Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.
Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.
If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, 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: If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.
Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .
Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.
If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views.

For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.
Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| MaxRows | Specifies the maximum rows returned for queries without aggregation or GROUP BY. |
| ODataVersion | The version of OData to use. By default the provider will attempt to autodetect the version. |
| Other | Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties. |
| Pagesize | Specifies the maximum number of results to return from SAP HANA XSA, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases. |
| ParametersEntitySets | The comma separated list of the renamed parameter entity sets for the exposed parameterized calculated views. |
| PseudoColumns | Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property. |
| SupportsExpand | Whether you need to specify the base entity's key to query navigation property views. |
| SupportsFormulas | A boolean indicating whether the OData service supports server side formulas. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout. |
| UseClientSidePaging | Whether or not the CData ADO.NET Provider for SAP HANA XSA should use client side paging. |
| UseEtags | Whether or not the OData source uses Etags. |
| UserDefinedViews | Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file. |
| UseSimpleNames | Boolean determining if simple names should be used for tables and columns. |
Specifies the maximum rows returned for queries without aggregation or GROUP BY.
This property sets an upper limit on the number of rows the Sync App returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.
When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.
This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.
The version of OData to use. By default the provider will attempt to autodetect the version.
The version of OData to use. By default the Sync App will automatically attempt to determine the version the service is using. If a version cannot be resolved, 3.0 will be used. This can optionally be manually set.
Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.
This property allows advanced users to configure hidden properties for specialized scenarios. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. Multiple properties can be defined in a semicolon-separated list.
Note: It is strongly recommended to set these properties only when advised by the support team to address specific scenarios or issues.
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. |
Specifies the maximum number of results to return from SAP HANA XSA, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases.
You may want to adjust the default pagesize to optimize results for a particular object or service endpoint you are querying. Be aware that increasing the page size may improve performance, but it could also result in higher memory consumption per page.
The comma separated list of the renamed parameter entity sets for the exposed parameterized calculated views.
You can provide the parameters entity set names as a comma separated list for the exposed calculated views that you are either using a renamed parameters entity set or a renamed Results navigation property.
Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.
This property allows you to define which pseudocolumns the Sync App exposes as table columns.
To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"
To include all pseudocolumns for all tables use: "*=*"
Whether you need to specify the base entity's key to query navigation property views.
This connection property is primarily used with limited OData APIs; it determines whether navigation properties can be retrieved from the base entity set. In OData, navigation properties link a base entity to a related entity or a collection of related entities.
For more on navigation properties, see Data Model.
In OData, the $expand parameter is used to expand specified navigation properties when requesting data from a given entity set. In SQL, this makes it possible to execute a SELECT * to a navigation property view.
If $expand is not supported, a different request must be made to retrieve a navigation property, one that specifies the primary key of the base entity set. This API restriction is reflected in SQL: You will need to specify the base entity's primary key in the WHERE clause.
For example, consider two entities with a one-to-many relationship in the Northwind sample service, Categories and Products. In OData, the Products associated with a given Category could be represented as a navigation property on the base Category entity set. The Sync App models the Products navigation property as a Categories_Products view.
If $expand is not supported, use a query like the following to this view:
SELECT * FROM Categories_Products WHERE (Categories_CategoryID = 1)
A boolean indicating whether the OData service supports server side formulas.
OData has many server-side formulas that are built into the specifications. However, many services do not natively support them and will return errors when these formulas are appended to the $filter parameter. When supported, server-side formulas can be used to execute certain queries much faster. If your OData service supports formulas, set this connection property to true. Otherwise, leave it as false.
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.
This property controls the maximum time, in seconds, that the Sync App waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the Sync App cancels the operation and throws an exception.
The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.
Setting this property to 0 disables the timeout, allowing operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.
Whether or not the CData ADO.NET Provider for SAP HANA XSA should use client side paging.
Some sources do not support server side paging. In these cases, set UseClientSidePaging to true. Otherwise, leave it as false. Setting UseClientSidePaging to true on a source that already supports paging can cause incomplete results.
Whether or not the OData source uses Etags.
Some OData sources do not use Etags. In these instances, set UseEtags to False.
Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.
This property allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the Sync App and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view. For example:
{
"MyView": {
"query": "SELECT * FROM SampleTable WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
You can define multiple views in a single file and specify the filepath using this property. For example: UserDefinedViews=C:\Path\To\UserDefinedViews.json. When you use this property, only the specified views are seen by the Sync App.
Refer to User Defined Views for more information.
Boolean determining if simple names should be used for tables and columns.
SAP HANA XSA tables and columns can use special characters in names that are normally not allowed in standard databases. UseSimpleNames makes the Sync App easier to use with traditional database tools.
Setting UseSimpleNames to true will simplify the names of tables and columns returned. It will enforce a naming scheme such that only alphanumeric characters and the underscore are valid for the displayed table and column names. Any nonalphanumeric characters will be converted to an underscore.
