MORE INFORMATION

This issue occurs because the sp_MStablekeys system stored procedure sometimes returns logically incorrect results. Because you use sp_MStablekeys to script out a table and its constraints, you end up generating incorrect script for table constraints.

For this reason, you can experience this problem in other scenarios where this system stored procedure is used. For example, you might experience this problem with replication. Replication uses the sp_MStablekeys stored procedure to script out the tables that are marked for replication (on the publisher) to create those tables on the subscriber. When the Distribution Agent tries to create a primary key on the subscriber that is based on the generated script from the publisher, it will fail, and you receive this error message:
Cannot use empty object or column names

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
