SQLDescribeParam

The SQLDescribeParam function returns the description of a parameter marker that is associated with a prepared SQL statement.

Parameter markers must appear in the correct ODBC locations, as specified in the Microsoft ODBC 2.0 Programmer's Reference and SDK Guide. Also, the driver does not support the following items:

• Calling SQLDescribeParam after execution.
• The Transact-SQL FROM clause extension to UPDATE and DELETE statements.
• Parameter markers in a subquery.
• Parameter markers in both expressions of a comparison, like, or quantified predicate.
