Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
The SQL Server Native Client ODBC driver supports all defined values for the Option argument in the SQLFreeStmt ODBC API function. However, it is best not to use SQLFreeStmt in ODBC 3.0 or in later versions of ODBC.
The SQLCloseCursor, SQLBindParameter, SQLBindCol, SQLSetDescField, and SQLFreeHandle ODBC API functions replace or duplicate the function of SQLFreeStmt. Therefore, we recommend that you use these functions instead of the SQLFreeStmt function.
