![]() For more information, see About Log Shipping. If the database is involved in log shipping, remove log shipping before dropping the database. ![]() If a database is damaged or replication cannot first be removed or both, in most cases you still can drop the database by using ALTER DATABASE to set the database offline and then dropping it. To drop a database published for transactional replication, or published or subscribed to merge replication, you must first remove replication from the database. This message is logged every five minutes as long as the cache is flushed within that time interval. For each cleared cachestore in the plan cache, the SQL Server error log contains the following informational message: " SQL Server has encountered %d occurrence(s) of cachestore flush for the '%s' cachestore (part of plan cache) due to some database maintenance or reconfigure operations". Clearing the plan cache causes a recompilation of all subsequent execution plans and can cause a sudden, temporary decrease in query performance. Dropping a database snapshot clears the plan cache for the instance of SQL Server. For information about using sparse files by database snapshots, see Database Snapshots. SQL Serverĭropping a database snapshot deletes the database snapshot from an instance of SQL Server and deletes the physical NTFS File System sparse files used by the snapshot. Applies to: SQL Server 2016 (13.x) through current version. For more information, see SQL Server Backup and Restore with Microsoft Azure Blob Storage. The file will be truncated, but will not be physically deleted in order to keep the FILE_SNAPSHOT backups intact. To remove a database from the current server without deleting the files from the file system, use sp_detach_db.ĭropping a database that has FILE_SNAPSHOT backups associated with it will succeed, but the database files that have associated snapshots will not be deleted to avoid invalidating the backups referring to these database files. These files can be deleted manually by using Windows Explorer. If the database or any one of its files is offline when it is dropped, the disk files are not deleted. When a database is dropped, the master database should be backed up.ĭropping a database deletes the database from an instance of SQL Server and deletes the physical disk files used by the database. Database snapshots cannot be backed up and, therefore, cannot be restored. To display the current state of a database, use the sys.databases catalog view.Ī dropped database can be re-created only by restoring a backup. General RemarksĪ database can be dropped regardless of its state: offline, read-only, suspect, and so on. ![]() Specifies the name of a database snapshot to be removed.
