Dropping a Microsoft SQL Server database

You can drop a database on an Amazon RDS DB instance running Microsoft SQL Server in a Single-AZ or Multi-AZ deployment. To drop the database, use the following command:

--replace your-database-name with the name of the database you want to drop
EXECUTE msdb.dbo.rds_drop_database  N'your-database-name'

After you use this procedure to drop the database, Amazon RDS drops all existing connections to the database and removes the database's backup history.
