Unable to get Not NULL parameter with SQLDescribeCol

[lupien1]

We need to retreive the NOT NULL column configuration on a table MSaccess database. We use the SQLDescribeCol function and the last parameter that is supposed to tell us if a column allow NOT NULL value without success. It always returning the same result.

Is there a known problem between SqlDescribeCol and MSACCESS and how can i retreive the NOT NULL column information?

Thank you.
