SYMPTOMSWhen 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.
