DROP DATABASE
Syntax
DROP {DATABASE | SCHEMA} [IF EXISTS] db_name
Contents
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 starting with 10.6.1
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
