ODBC Driver for xBase

Supported ODBC API Functions



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 ODBC Driver for xBase. To obtain information about support for a specific function in the driver, an application can call SQLGetFunctions.

Important Note:

For backward compatibility, ODBC Driver for xBase supports all deprecated functions.
