This article describes how to delete a user-defined database in SQL Server by using SQL Server Management Studio or Transact-SQL.
Prerequisites
Delete any database snapshots that exist on the database. For more information, see Drop a Database Snapshot.
If the database is involved in log shipping, remove log shipping.
If the database is published for transactional replication, or published or subscribed to merge replication, remove replication from the database.
Warning
Consider taking a full backup of the database before dropping it. You can recreate a deleted database only by restoring a full backup. For more information, see Quickstart: Backup and restore a SQL Server database with SSMS.
Permissions
To run DROP DATABASE, you need CONTROL permission on the database.
Use SQL Server Management Studio
In Object Explorer, connect to an instance of the SQL Server Database Engine, and then expand that instance.
Expand Databases, right-click the database to delete, and then select Delete.
Confirm the correct database is selected, and then select OK.
Use Transact-SQL
For more information, see DROP DATABASE.
Connect to the Database Engine.
From the Standard bar, select New Query.
Copy and paste the following example into the query window and select Execute. This example removes the
SalesandNewSalesdatabases.
USE master;
GO
DROP DATABASE Sales, NewSales;
Follow up: After deleting a database
Back up the master database. If you need to restore master, any database that you deleted since the last backup of master still has references in the system catalog views and might cause error messages.
Limitations
You can't delete system databases. For more information, see DROP DATABASE.
