BUG #: 469206 (SQL Server 8.0)

SYMPTOMS

After you upgrade to Microsoft SQL Server 2000 post-Service Pack 2 (SP2) or a later build including SQL Server 2000 SP3, a query may take a much longer time to run, even though the query runs in seconds in SQL Server 2000 SP2. This problem occurs if both the following conditions are true:
  • The query has multitable joins, and one of the joins is a view.
  • The view has multitable joins, and a corelated subquery.
