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 updates that were included with the previous SQL Server 2008 R2 update release.

SYMPTOMS

Consider the following scenario:
  • You create two or more partitions on a column of a table in Microsoft SQL Server 2008 R2.
  • You create a clustered index on a different column of the same table.
  • You run a query against the table. The query uses two or more of the partitions.

In this scenario, slow performance occurs, and a sort operation is used in the execution plan instead of the clustered index.
