Microsoft distributes Microsoft SQL Server 2008 R2 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 2008 R2 fix release.

Symptoms

Consider the following scenario:

  • You create a partitioned view in SQL Server 2008 R2. For example, you create a partitioned view named View, and you define the CHECK constraints for the ColA column in the member tables of View1.

  • You create a clustered index for a column in the member tables of the partitioned view. For example, you create a clustered index for the ColB column in the member tables of View1.

  • You create a composite nonclustered index on multiple columns in the member tables. These columns include the columns that have a clustered index. For example, you create a nonclustered index on the ColA, ColB, and other columns in the member tables of View1.

  • You run an UPDATE statement against View1 to update the ColA column by using a predicate for the ColB column in the WHERE clause.

In this scenario, you receive the following error message when you run the statement:

Msg 208, Level 16, State 1, Line 1Invalid object name 'View1'.

Additionally, a mini-dump file is generated in the SQL Server log folder. Also, an error message that resembles the following is logged for index corruption in the SQL Server Errorlog file:

Cause

This issue occurs because of a regression in the query optimizer in SQL Server 2008 R2.
