Syntax

DROP DATABASE [IF EXISTS] <database_name> [FORCE]

DROP SCHEMA [IF EXISTS] <database_name> [FORCE]

DROP DETACHED DATABASE <database_name> [STORAGEID <storage_id>] [COMPUTEID <compute_id>]

Arguments

• <database_name>: The name of a SingleStore database.

• <storage_id> (Optional): The STORAGE_ID extracted from information_schema.MV_CLOUD_BRANCHES for the respective database.

• <compute_id> (Optional): The LATEST_COMPUTE_ID extracted from information_schema.MV_CLOUD_BRANCHES for the respective database.

Remarks

• By default, the DROP DATABASE command waits for the running queries to finish before dropping the database. To override this behavior and kill any running queries, use the FORCE option.

• This command causes implicit commits. Refer to COMMIT for more information.

• The DROP DATABASE command cannot be run on system databases.

• The DROP DATABASE command drops the Point-In-Time Recovery (PITR) history. A database cannot be restored to the PITR milestone taken before the database was dropped.

• The DROP DETACHED DATABASE command drops a database which was previously detached.

• In the DROP DETACHED DATABASE command, the STORAGEID and COMPUTEID clauses apply when multiple entries exist in information_schema.MV_CLOUD_BRANCHES for the same database name.

• Refer to the Permission Matrix for the required permission.

Dropping a Database in a Workspace

Executing  DROP DATABASE in a workspace can be only done from the primary R/W database. If a database is detached, it can be dropped in the cloud portal by selecting Drop Database from the three dots (ellipsis) in the database card under Deployments > Overview. If this command is run on the primary R/W database it will drop the database from all the workspaces including the read-only copies.

Examples

DROP DATABASE IF EXISTS test;

DROP DATABASE IF EXISTS db FORCE;

DROP DETACHED DATABASE testdb;

SELECT STORAGE_ID, LATEST_COMPUTE_ID FROM information_schema.MV_CLOUD_BRANCHES
WHERE DATABASE_NAME=‘testdb’;

DROP DETACHED DATABASE testdb STORAGEID 6362647530070456236:6577025878327007897 COMPUTEID 16245003384144080785:18098;
