SHOW OPEN TABLES

Sintassi

SHOW OPEN TABLES [FROM nome_db]
    [LIKE 'pattern' | WHERE espr]

Spiegazione

SHOW OPEN TABLES restituisce le tabelle non temporanee che sono attualmente aperte nella cache delle tabelle. Si veda http://dev.mysql.com/doc/refman/5.1/en/table-cache.html.

Le clausole FROM e LIKE possono essere utilizzate in MariaDB e a partire da MySQL 5.1.24.

La clausola FROM, se presente, mostra solo le tabelle contenute in nome_db.

La clausola LIKE, se presente, mostra solo le tabelle i cui nomi corrispondono al pattern. La clausola WHERE si usa per specificare condizioni più generiche, come spiegato in http://dev.mysql.com/doc/refman/5.1/en/extended-show.html.
