DROP DATABASE

Sintassi

DROP {DATABASE | SCHEMA} [IF EXISTS] nome_db

Spiegazione

DROP DATABASE elimina il database specificato e tutte le tabelle in esso contenute. Occorre prestare molta attenzione! Per usare DROP DATABASE, occorre disporre del privilegio DROP sul database interessato. DROP SCHEMA è sinonimo di DROP DATABASE.

Importante: Quando un database viene eliminato, i permessi degli utenti relativi a quel database non vengono cancellati. Si veda GRANT.

IF EXISTS serve ad evitare che venga generato un errore se il database non esiste.

Esempio

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

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
