# Accessing the tempdb database on Microsoft SQL Server DB instances on Amazon RDS
<a name="SQLServer.TempDB"></a>

You can access the `tempdb` database on your Microsoft SQL Server DB instances on Amazon RDS. You can run code on `tempdb` by using Transact-SQL through Microsoft SQL Server Management Studio (SSMS), or any other standard SQL client application. For more information about connecting to your DB instance, see [Connecting to your Microsoft SQL Server DB instance](USER_ConnectToMicrosoftSQLServerInstance.md). 

The master user for your DB instance is granted `CONTROL` access to `tempdb` so that this user can modify the `tempdb` database options. The master user isn't the database owner of the `tempdb` database. If necessary, the master user can grant `CONTROL` access to other users so that they can also modify the `tempdb` database options. 

**Note**  
You can't run Database Console Commands (DBCC) on the `tempdb` database.
