MySQL Connector/ODBC Release Notes
This section summarizes ODBC routines, categorized by functionality.
For the complete ODBC API reference, please refer to the ODBC Programmer's Reference at http://msdn.microsoft.com/en-us/library/ms714177.aspx.
An application can call SQLGetInfo function
to obtain conformance information about Connector/ODBC. To obtain
information about support for a specific function in the driver,
an application can call SQLGetFunctions.
Note
For backward compatibility, the Connector/ODBC driver supports all deprecated functions.
