FIX: You receive an incorrect value when you query the last-inserted identity value after you use a client-side cursor to insert data to a table that contains an identity column in an application that uses ActiveX Data Objects
In an instance of Microsoft SQL Server, you have two tables, and each table contains an identity column.
You create an INSERT trigger on the first table. The trigger inserts data to the second table when the trigger executes.
You have an application that uses Microsoft ActiveX Data Objects (ADO) to connect to the instance of SQL Server.
In the application, you use a client-side cursor to insert data to the first table.
In this scenario, when you run the application and then query the last-inserted identity value, you may find that the function returns an incorrect value. The value corresponds to the auto-increment value that is generated on the second table instead of on the first table.
This problem occurs in the Microsoft Data Access Components (MDAC) 2.8. You may have MDAC 2.8 installed on one of the following Windows operating systems:
Windows XP Service Pack 2 (SP2)
Windows XP Service Pack 3 (SP3)
Windows Server 2003 Service Pack 1 (SP1)
Windows Server 2003 Service Pack 2 (SP2)
Windows Vista Service Pack 1 (SP1)
Windows Server 2008
When data is inserted in the first table, the insert trigger uses the @@IDENTITY function instead of the SCOPE_IDENTITY function to obtain the last-inserted identity value. Therefore, the @@IDENTITY function may return an identity value that is not generated by the same table.
