Miscellaneous
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| AllowUserVariables | Specifies whether user-defined variables (prefixed with @) are allowed in SQL queries. When enabled, the driver treats these as in-query user variables instead of parameter placeholders, allowing advanced SQL scripting patterns, such as variable assignment and conditional logic. |
| Characterset | Specifies the default client character set used by the provider for encoding queries it sends to the server. |
| DateTimeTimeZone | Specifies the timezone to apply to DATETIME types. |
| EnsureKeepAlive | Setting this property to 'true' means that provider pings the server before performing a request, so the driver knows if the connection has been dropped since the last request. |
| MaxRows | Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY. |
| Other | Specifies additional hidden properties for specific use cases., to be used only when our Support team advises it, to address specific issues. See Remarks for details. |
| QueryPassthrough | This option passes the query to the MySQL server as is. |
| Readonly | Toggles read-only access to MySQL from the provider. |
| RTK | Specifies the runtime key for licensing the provider. If unset or invalid, the provider defaults to the standard licensing method. This property is only required in environments where the standard licensing method is unsupported or requires a runtime key. |
| ServerTimeZone | Specifies the timezone identifier for the MySQL server, based on the current edition and platform. This setting controls how the driver interprets and converts datetime values between the server and client. |
| Timeout | This setting defines how long (in seconds) an operation is allowed to run before the system automatically considers it as having timed out. If the operation does not finish within the specified time, a timeout error is thrown. The default value is set to 30 seconds. |
| TinyInt1Type | Defines the presentation type used to display small integer values. |
| ZeroDatesToNull | This property determines whether Date and DateTime values consisting entirely of zeros (for example, '0000-00-00' or '0000-00-00 00:00:00') are returned as NULL values. By default, this property is set to 'true', meaning any invalid date or datetime values represented as all zeros is returned as NULL instead of their original value. |
