Adding a Connection to MySQL

To add a connection to MySQL:

1. In the application console, navigate to the Connections page.
2. At the Add Connections panel, select the icon for the connection you want to add.
3. If the MySQL icon is not available, click the Add More icon to download and install the MySQL connector from the CData site.

For required properties, see the Settings tab.

For connection properties that are not typically required, see the Advanced tab.

Connecting to MySQL

To connect to MySQL data, set the following properties:

• Server: The host name or IP of the server hosting the MySQL database.
• Port: The port of the server hosting the MySQL database.
• Database (optional): The default database to connect to when connecting to the MySQL Server. If this is not set, MySQL returns tables from all available databases.

Authenticating to MySQL

MySQL supports the following types of authentication:

• Standard
• NT Lan Manager (NTLM)
• LDAP
• SSL
• SSH
• Azure
• AWS

Standard Authentication

To authenticate using standard authentication, set AuthScheme to Password and set the following properties:

• User: The username of the authenticating MySQL user.
• Password: The password associated with the authenticating MySQL user.

NTLM

To authenticate using NTLM, set AuthScheme to NTLM.

By default, the Sync App determines user credentials and the NTLM domain automatically, using either the domain of the PC it is running on or the domain used by the machine running the MySQL instance. To discover the user credentials, the Sync App reads the current NTLM user.

If you want to specify a different domain, provide different login credentials, or change the target NTLM version via any or all of the following optional properties:

• User: The authenticating NTLM user.
• Password: The authenticating NTLM user's password.
• Domain: The name of the domain you want to connect to.
• NTLMVersion: The NTLM version used by the Sync App. Legal values are 1 (default) and 2.

LDAP

To authenticate as an LDAP user, set AuthScheme to LDAP.

Your LDAP credentials are auto-detected by default. If you want to designate a different user and account, set the following optional properties:

• User: The user to login as.
• Password: The user's password.

SSL

To leverage SSL authentication to connect securely to MySQL data, set these properties:

• SSLClientCert: The name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: The client certificate store's password. Required if the certificate store is password-protected.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSLClientCertType:; The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

SSH

To authenticate to a remote machine via SSH and access MySQL data, set these properties:

• SSHClientCert: The name of the certificate store for the client certificate.
• SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSHClientCertType: The certificate type of the client store.
• SSHPassword: The password that you use to authenticate with the SSH server.
• SSHPort: The port used for SSH operations.
• SSHServer: The SSH authentication server you are trying to authenticate against.
• SSHServerFingerPrint: The SSH Server fingerprint used to verify the host you are connecting to.
• SSHUser: The username for authenticating to the SSH server.

MySQL on Azure

You can authenticate to a MySQL database hosted on Azure AD as an Azure AD user (using Azure AD user credentials), using Azure MSI (using a Managed Service Identity), or via an Azure Password. The following table describes required connection parameters for all three authschemes.

	Parameter	Set To...	Notes
Azure AD user	AzureTenant	The Microsoft Online tenant where MySQL is located.	See Note 1.
	AuthScheme	AzureAD	See Note 2.
Azure MSI	AzureTenant	The Microsoft Online tenant where MySQL is located.	See Note 1.
	AuthScheme	AzureMSI	Most often used when MySQL is running on an Azure VM.
	OAuthClientId	Managed identity's client_identity	Required to obtain a token for a managed identity or if the VM has multiple user-assigned managed identities.
Azure Password	AuthScheme	AzurePassword	To connect directly using your Azure credentials, specify the User and Password of the account you use to connect to Azure.

Notes

1. AzureTenant is generally supplied in the form companyname.microsoft.com, but it is also acceptable to specify the tenant Id. (The tenant Id is the same as the directory Id shown in the Azure Portal Azure Active Directory > Properties page.)

   When OAuthGrantType is set to CODE (the default), AzureTenant is usually not needed unless the user belongs to multiple tenants. When OAuthGrantType is set to CLIENT, AzureTenant is required.

2. The AzureAD AuthScheme is generally used with a custom OAuth application to establish the required OAuth credentials. These usually take the form of an account identifier or cllient ID, and the account password or client secret.

MySQL on AWS

You can connect to a MySQL database hosted on AWS using either IAM roles or EC2 roles.

AWS IAM Roles

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:

• AWSAccessKey: The access key of the IAM user to assume the role for.
• AWSSecretKey: The secret key of the IAM user to assume the role for.
• AWSRoleARN: Specify the Role ARN for the role you'd like to authenticate with. This will cause the Sync App to attempt to retrieve credentials for the specified role.

If multi-factor authentication is required, specify the following:

• CredentialsLocation: The location of the settings file where MFA credentials are saved. See the Credentials File Location page under Connection String Options for more information.
• MFASerialNumber: The serial number of the MFA device if one is being used.
• MFAToken: The temporary token available from your MFA device.

This causes the Sync App to submit the MFA credentials in the request to retrieve temporary authentication credentials.

Note: If you want to control the duration of the temporary credentials, set the TemporaryTokenDuration property (default: 3600 seconds).

EC2 Instances

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 set AWSRoleARN to the Role ARN for the role you want to authenticate with.

IMDSv2 Support

The MySQL 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 MySQL 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.

This section details a selection of advanced features of the MySQL Sync App.

SSL Configuration

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" .

Firewall and Proxy

Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies. You can also set up tunnel connections.

Logging

For an overview of configuration settings that can be used to refine CData logging, see Logging. Only two connection properties are required for basic logging, but there are numerous features that support more refined logging, which enables you to use the LogModules connection property to specify subsets of information to be logged.

Customizing the SSL Configuration

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.

Client SSL Certificates

The MySQL Sync App also supports setting client certificates. Set the following to connect using a client certificate.

• SSLClientCert: The name of the certificate store for the client certificate.
• SSLClientCertType: The type of key store containing the TLS/SSL client certificate.
• SSLClientCertPassword: The password for the TLS/SSL client certificate.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate.

Connecting Through a Firewall or Proxy

Set the following properties:

• To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
• To tunnel the connection, set FirewallType to TUNNEL.
• To authenticate, specify FirewallUser and FirewallPassword.
• To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

The connection string properties are the various options that can be used to establish a connection. This section provides a complete list of the options you can configure in the connection string for this provider. Click the links for further details.

Use this property alongside SSLClientCertType, which defines the type of the certificate store, and SSLClientCertPassword, which specifies the password for password-protected stores. When SSLClientCert is set and SSLClientCertSubject is configured, the driver searches for a certificate matching the specified subject.

Certificate store designations vary by platform. On Windows, certificate stores are identified by names such as MY (personal certificates), while in Java, the certificate store is typically a file containing certificates and optional private keys.

The following are designations of the most common User and Machine certificate stores in Windows:

MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.
SPC	Software publisher certificates.

For PFXFile types, set this property to the filename. For PFXBlob types, set this property to the binary contents of the file in PKCS12 format.

Specifies the type of key store containing the TLS/SSL client certificate for SSL Client Authentication. Choose from a variety of key store formats depending on your platform and certificate source.

Remarks

This property determines the format and location of the key store used to provide the client certificate. Supported values include platform-specific and universal key store formats. The available values and their usage are:

USER - default	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note that this store type is not available in Java.
MACHINE	For Windows, this specifies that the certificate store is a machine store. Note that this store type is not available in Java.
PFXFILE	The certificate store is the name of a PFX (PKCS12) file containing certificates.
PFXBLOB	The certificate store is a string (base-64-encoded) representing a certificate store in PFX (PKCS12) format.
JKSFILE	The certificate store is the name of a Java key store (JKS) file containing certificates. Note that this store type is only available in Java.
JKSBLOB	The certificate store is a string (base-64-encoded) representing a certificate store in JKS format. Note that this store type is only available in Java.

Specifes the password required to access the TLS/SSL client certificate store. Use this property if the selected certificate store type requires a password for access.

Remarks

This property provides the password needed to open a password-protected certificate store. This property is necessary when using certificate stores that require a password for decryption, as is often recommended for PFX or JKS type stores.

If the certificate store type does not require a password, for example USER or MACHINE on Windows, this property can be left blank. Ensure that the password matches the one associated with the specified certificate store to avoid authentication errors.

Specifes the subject of the TLS/SSL client certificate to locate it in the certificate store. Use a comma-separated list of distinguished name fields, such as CN=www.server.com, C=US. The wildcard * selects the first certificate in the store.

Remarks

This property determines which client certificate to load based on its subject. The Sync App searches for a certificate that exactly matches the specified subject. If no exact match is found, the Sync App looks for certificates containing the value of the subject. If no match is found, no certificate is selected.

The subject should follow the standard format of a comma-separated list of distinguished name fields and values. For example, CN=www.server.com, OU=Test, C=US. Common fields include the following:

Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

Note: If any field contains special characters, such as commas, the value must be quoted. For example: CN="Example, Inc.", C=US.

Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Remarks

This property can take the following forms:

Description	Example
A full PEM Certificate (example shortened for brevity)	-----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE-----
A path to a local file containing the certificate	C:\cert.cer
The public key (example shortened for brevity)	-----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY-----
The MD5 Thumbprint (hex values can also be either space or colon separated)	ecadbdda5a1529c58a1e9e09828d70e4
The SHA1 Thumbprint (hex values can also be either space or colon separated)	34a929226ae0819f2ec14b4a3d904f801cbb150d

If not specified, any certificate trusted by the machine is accepted.

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

The authentication method used when establishing an SSH Tunnel to the service.

Remarks

• None: No authentication is performed. The current SSHUser value is ignored, and the connection is logged in as anonymous.
• Password: The Sync App uses the values of SSHUser and SSHPassword to authenticate the user.
• Public_Key: The Sync App uses the values of SSHUser and SSHClientCert to authenticate the user. SSHClientCert must have a private key available for this authentication method to succeed.

A certificate to be used for authenticating the SSHUser.

Remarks

SSHClientCert must contain a valid private key in order to use public key authentication. A public key is optional, if one is not included then the Sync App generates it from the private key. The Sync App sends the public key to the server and the connection is allowed if the user has authorized the public key.

The SSHClientCertType field specifies the type of the key store specified by SSHClientCert. If the store is password protected, specify the password in SSHClientCertPassword.

Some types of key stores are containers which may include multiple keys. By default the Sync App will select the first key in the store, but you can specify a specific key using SSHClientCertSubject.

The password of the SSHClientCert key if it has one.

Remarks

This property is required for SSH tunneling when using certificate-based authentication. If the SSH certificate is in a password-protected key store, provide the password using this property to access the certificate.

The subject of the SSH client certificate.

Remarks

When loading a certificate the subject is used to locate the certificate in the store.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks the first certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, [email protected]". Common fields and their meanings are displayed below.

Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

If a field value contains a comma it must be quoted.

The type of SSHClientCert private key.

Remarks

This property can take one of the following values:

Types	Description	Allowed Blob Values
MACHINE/USER		Blob values are not supported.

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.

Remarks

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.

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 MySQL. Traffic flows back and forth via the proxy at this location.
SOCKS4	1080	The port where the Sync App opens a connection to MySQL. 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 MySQL. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes.

Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.

This section provides a complete list of the Proxy properties you can configure in the connection string for this provider.

---

Property	Description
ProxyAutoDetect	Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.
ProxyServer	The hostname or IP address of the proxy server that you want to route HTTP traffic through.
ProxyPort	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.
ProxyAuthScheme	Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.
ProxyUser	The username of a user account registered with the proxy server specified in the ProxyServer connection property.
ProxyPassword	The password associated with the user specified in the ProxyUser connection property.
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.

Remarks

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.

Remarks

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.

Remarks

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.

Remarks

The authentication type can be one of the following:

• BASIC: The Sync App performs HTTP BASIC authentication.
• DIGEST: The Sync App performs HTTP DIGEST authentication.
• NTLM: The Sync App retrieves an NTLM token.
• NEGOTIATE: The Sync App retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• NONE: Set this when the ProxyServer does not require authentication.

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.

Remarks

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.

Remarks

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 ProxyPassword
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.

Remarks

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.

Remarks

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.

Remarks

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.

Remarks

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\\MySQL 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 .

Remarks

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 .

Remarks

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 .

Remarks

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. To do this, 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: 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
AllowUserVariables	When set to True, user variables (prefixed by an @) can be used in SQL queries.
Characterset	The default client character set used by the provider. For example, 'utf8'.
EnsureKeepAlive	When set to True, a COM_PING is sent to check if the server is alive.
MaxRows	Specifies the maximum rows returned for queries without aggregation or GROUP BY.
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.
QueryPassthrough	This option passes the query to the MySQL server as is.
ServerTimeZone	Specify a specific server time zone id of current platform(.Net or Java) by user.
Timeout	The value in seconds until the connection timeout error is thrown.
TinyInt1Type	The TinyInt1 Type.
ZeroDatesToNull	Whether or not to return Date and DateTime values consisting of all zeros as NULL.

When set to True, user variables (prefixed by an @) can be used in SQL queries.

Remarks

When set to True, user variables (prefixed by an @) can be used in SQL queries. The default behavior is to treat identifiers prefixed with @ as command parameters.

The default client character set used by the provider. For example, 'utf8'.

Remarks

By default the client character set is determined from the server's language settings, but you can override that value by setting this option. This can be useful if you need to use a specific encoding or collation in your queries.

When set to True, a COM_PING is sent to check if the server is alive.

Remarks

When set to True, a COM_PING is sent to check if the server is alive. The default behavior is to not send a COM_PING.

Specifies the maximum rows returned for queries without aggregation or GROUP BY.

Remarks

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.

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.

Remarks

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.

Integration and Formatting

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.

This option passes the query to the MySQL server as is.

Remarks

When this is set, queries are passed through directly to MySQL.

Specify a specific server time zone id of current platform(.Net or Java) by user.

Remarks

Specify a specific server time zone id of current platform(.Net or Java) by user. When set to LOCAL, we assume the server timezone is the same as local, and don't apply any timezone conversion.

The value in seconds until the connection timeout error is thrown.

Remarks

If Timeout is 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.

The TinyInt1 Type.

Remarks

This property specifies the TinyInt1 type to use.

Whether or not to return Date and DateTime values consisting of all zeros as NULL.

Remarks

Whether or not to return Date and DateTime values consisting of all zeros as NULL. A value of all zeros indicates an invalid Date or DateTime value in MySQL. Retrieving such a value may cause parsing errors unless you set this property to True.
