SYMPTOMS

Consider the following scenario:

An application connects to one of the following products:
- Microsoft SQL Server 2005
- Microsoft SQL Server 2005 Express Edition
- Microsoft SQL Server 2000
- SQL Server Desktop Engine (also known as MSDE 2000)
The application uses the SET NOCOUNT ON statement for the connection.
The application uses a Microsoft ActiveX Data Objects (ADO) client-side cursor to insert a row into a table that has an identity column.

When the application queries the identity column value of the newly inserted row, the value "0" is returned incorrectly. When this value is returned, an application that uses the ActiveX Data Objects (ADO) interface may malfunction, or data loss may occur. Whether a malfunction or data loss occurs depends on how the application handles this scenario.

Note This problem occurs only if the application uses a client-side cursor. If the application uses a server-side cursor, the application is not affected.

This problem occurs in the Microsoft Data Access Components (MDAC) components of the following Windows operating systems:

Windows Vista Service Pack 1 (SP1)
Windows XP Service Pack 2 (SP2) with hotfix 940569
Windows XP Service Pack 3 (SP3)
Windows Server 2008
