AllowDBNull Property does not work

320111May 11 2004 — edited May 13 2004
Is there any way to determine if a column in a table returned from an OracleDataAdapter.Fill Method will allow Null? The DataTable.Columns.AllowDBNull Property returns True for every column, even those that have a constraint specifying NOT NULL.
