This article describes cumulative update package 6 for Microsoft SQL Server 2008 R2 Service Pack 1 (SP1). This update contains hotfixes for issues that were fixed after the release of SQL Server 2008 R2 SP1.

Note The build number of this cumulative update package is 10.50.2811.0.

We recommend that you test hotfixes before you deploy them in a production environment. Because the builds are cumulative, each new update release contains all the hotfixes and all the security updates that were included with the previous SQL Server 2008 R2 update release. We recommend that you consider applying the most recent update release that contains this hotfix.

Important notes about this cumulative update package

  • SQL Server 2008 hotfixes are now multilingual. Therefore, the cumulative update package is not specific to one language and applies to all supported languages.

  • One cumulative update package includes all the component packages. However, the cumulative update package updates only those components that are installed on the system.
