This section summarizes ODBC routines, categorized by functionality.
For the complete ODBC API reference, please refer to the ODBC Programmer's Reference at .
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.
For backward compatibility, the Connector/ODBC driver supports all deprecated functions.
The following tables list Connector/ODBC API calls grouped by task:
