SHOW EVENTS
Sintassi
SHOW EVENTS [{FROM | IN} nome_schema] [LIKE 'pattern' | WHERE espr]
Spiegazione
Nella sua forma più semplice, SHOW EVENTS
elenca tutti gli eventi presenti nello schema corrente:
MariaDB [(none)]> SELECT CURRENT_USER(), SCHEMA(); +----------------+----------+ | CURRENT_USER() | SCHEMA() | +----------------+----------+ | jon@ghidora | myschema | +----------------+----------+ 1 row in set (0.00 sec) MariaDB [test]> SHOW EVENTS\G *************************** 1. row *************************** Db: myschema Name: e_daily Definer: jon@ghidora Time zone: SYSTEM Type: RECURRING Execute at: NULL Interval value: 10 Interval field: SECOND Starts: 2006-02-09 10:41:23 Ends: NULL Status: ENABLED Originator: 0 character_set_client: latin1 collation_connection: latin1_swedish_ci Database Collation: latin1_swedish_ci
Per conoscere gli eventi contenuti in uno schema specifico, si usi la clausola FROM
.
Per esempio, per ottenere gli eventi presenti nel database test, si può eseguire:
SHOW EVENTS FROM test;
La clausola LIKE
, se presente, mostra solo gli eventi i cui nomi corrispondono al pattern. La clausola WHERE
può essere usata per specificare condizioni più generali, come spiegato in
