FIX: You may receive an "Internal SQL Server error" error message when you run a Transact-SQL SELECT statement on a view that has many subqueries in SQL Server 2000
View products that this article applies to.
Bug #: 470138 (SQL Server 8.0)
Microsoft distributes SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.
SYMPTOMS
When you run a Transact-SQL SELECT statement on a view that has many subqueries, you may receive an error message that is similar to the following:


Server: Msg 8624, Level 16, State 21, Line 1
Internal SQL Server error.
