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
Assume that you install Microsoft Visual Studio 2010 Service Pack 1 (SP1) on a computer that has Microsoft SQL Server 2008 R2 RTM and Cumulative Update 1 through 6 for Microsoft SQL Server 2008 R2 installed. In this situation, the IntelliSense feature in Microsoft SQL Server 2008 R2 Management Studio (SSMS 2008 R2) may stop working.
Note The IntelliSense feature provides suggestions for how to complete SQL queries. Additionally, the feature provides query validation when you create SQL queries in a query window in SSMS. When this issue occurs, SSMS 2008 R2 does not provide suggestions for how to complete queries and does not highlight errors in SQL queries by using red wavy lines.
Resolution
To resolve this issue, apply the following cumulative update. This cumulative update fixes the incompatibility between SSMS 2008 R2 and the Transact-SQL Language Service that is included in Visual Studio 2010 SP1.
Note If you install this cumulative update on the computer that has Visual Studio 2010 RTM installed, you may experience a loss of SQL IntelliSense features in Visual Studio. To resolve this issue, install Visual Studio 2010 SP1. To download this service pack, visit the following Microsoft website:
