FIX: The Check Database Integrity task and the Execute T-SQL Statement task in a maintenance plan may lose database context in certain circumstances in SQL Server 2005 builds 3150 through 3158

Extended support for SQL Server 2005 ends on April 12, 2016

If you are still running SQL Server 2005 after April 12, 2016, you will no longer receive security updates and technical support. We recommend upgrading to SQL Server 2014 and Azure SQL Database to achieve breakthrough performance, maintain security and compliance, and optimize your data platform infrastructure. Learn more about the options for upgrading from SQL Server 2005 to a supported version here.

Symptoms
In Microsoft SQL Server 2005 Service Pack 2 (SP2), the following tasks in a maintenance plan may lose database context in certain circumstances:
  • Check Database Integrity
  • Execute T-SQL Statement
For example, if a Check Database Integrity task is configured to check integrity on multiple databases, the task repeatedly checks the default database.

For the Execute T-SQL Statement task, this problem occurs if the following conditions are true:
  • The Execute T-SQL Statement task contains multiple batches.
  • The batches are separated by the GO statement.
  • No batches use the USE statement to specify the database.
  • The statements in each batch do not contain the database name.
In this scenario, those statements in the second batch and in succeeding batches will be executed against the default database.

Note You can confirm that this problem has occurred by using SQL Server Profiler. When you trace the maintenance plan execution, see the Database column in SQL Server Profiler.
Resolution
This problem occurs in SQL Server 2005 builds 3042 through 3053 and in SQL Server 2005 builds 3150 through 3158. If you are running a build of SQL Server 2005 SP2 between 3150 and 3158, download and install the following file from the Microsoft Download Center.

Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
More information
In the original release version of SQL Server 2005 SP2 and earlier versions, commands that are related to maintenance plan tasks are accumulated and then executed at the same time. When an error occurs, tasks are no longer executed, and the remaining maintenance tasks are not performed. In SQL Server 2005 SP2, individual batches are submitted one at a time. In the original release version of SQL Server 2005 SP2, the database connection was reset between batches. Later batches were left in the context of the default database instead of in the context that was present before the GO statement was executed. The tasks that were affected depended on the context that was present before the GO statement was executed, specifically the Check Database Integrity task and the Execute T-SQL Statement task.

This hotfix is also included in the cumulative update package (build 3161) for SQL Server 2005 Service Pack 2. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
