BUG: Access ODBC: SQLGetInfo(SQL_NON_NULLABLE_COLUMNS)

SYMPTOMS

Calling SQLGetInfo with InfoType=SQL_NON_NULLABLE_COLUMNS for Microsoft Access ODBC driver returns the value as SQL_NNC_NON_NULL, which implies that the columns may be non-nullable and that the data source supports the NOT NULL column constraint in CREATE TABLE statement. However, the Microsoft Access ODBC driver does not allow NON NULL constraint in the CREATE TABLE. Therefore, the value returned should be SQL_NNC_NULL to indicate that all columns must be nullable.
