Delete a Database

  • Artikkeli

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

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 (Transact-SQL).

  • 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. A deleted database can be re-created only by restoring a full backup. For more information, see Quickstart: Backup and restore a SQL Server database on-premises.

Security

Permissions

To execute DROP DATABASE, at a minimum, a user must have CONTROL permission on the database.

Follow Up: After deleting a database

Back up the master database. If master must be restored, any database that has been deleted since the last backup of master will still have references in the system catalog views and may cause error messages to be raised.
