DROP DATABASE
Syntax
DROP {DATABASE | SCHEMA} [IF EXISTS] db_name
Description
DROP DATABASE
drops all tables in the database and deletes the database. Be very careful with this statement! To use DROP DATABASE, you need the DROP privilege on the database. DROP SCHEMA
is a synonym for DROP DATABASE
.
Important: When a database is dropped, user privileges on the database are not automatically dropped. See GRANT.
IF EXISTS
Use IF EXISTS
to prevent an error from occurring for databases that do not exist. A NOTE
is generated for each non-existent database when using IF EXISTS
. See SHOW WARNINGS.
Atomic DDL
MariaDB 10.6.1 supports Atomic DDL.
DROP DATABASE
is implemented as
loop over all tables DROP TABLE table
Each individual DROP TABLE is atomic while DROP DATABASE
as a whole is crash-safe.
Examples
DROP DATABASE bufg; Query OK, 0 rows affected (0.39 sec) DROP DATABASE bufg; ERROR 1008 (HY000): Can't drop database 'bufg'; database doesn't exist \W Show warnings enabled. DROP DATABASE IF EXISTS bufg; Query OK, 0 rows affected, 1 warning (0.00 sec) Note (Code 1008): Can't drop database 'bufg'; database doesn't exist
