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)

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 http://dev.mysql.com/doc/refman/5.1/en/extended-show.html.
