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.
