SYMPTOMS

When you run a query against Microsoft SQL Server 2000 post-Service Pack 3 (SP3) hotfix build 8.00.0988, the query may run more slowly than a query that you run against SQL Server 2000 post-SP3 hotfix builds that are earlier than build 8.00.0988.

This problem also occurs when you run queries against Microsoft SQL Server 2000 post-Service Pack 4 (SP4) hotfix builds.

This problem occurs when all the following conditions are true:
  • The query references a view.
  • The definition of the view contains both a UNION ALL clause and an ORDER BY clause.

RESOLUTION

The installer does not install this hotfix correctly on x64-based systems. This installation issue occurs when the following conditions are true:
  • The system uses the Advanced Micro Devices (AMD) AMD64 processor architecture or the Intel Extended Memory 64 Technology (EM64T) processor architecture.

    Note This issue does not occur on systems that use the Intel Itanium processor architecture.
  • The system is running a 64-bit version of the Microsoft Windows Server operating system.
  • The system is running a 32-bit version of SQL Server 2000.
We have corrected this installation issue in later builds of SQL Server 2000, starting with version 8.00.2244. When a customer who is running SQL Server 2000 on an x64-based system requests this hotfix, we will provide a build that includes this hotfix and that can be installed correctly on an x64-based system. The build that we provide will be version 8.00.2244 or a later version.
