BUG #: 15749 (2.65.0201)

SYMPTOMS

When you add an identity column to an existing table using the ALTER TABLE statement, SQLColAttributes and SQLDescribeCol incorrectly report that the identity column allows NULLs.

WORKAROUND

To work around this problem, use the Column nullability information derived from SQLColumns.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5 and the Open Database Connectivity driver version 2.65. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.

MORE INFORMATION

SQLColumns, correctly reports that the column does not allow NULLs.

NOTE: This problem also occurs with the SQL Server 6.5 Service Pack 1 ODBC driver build 2.65.0212.
