delete
dokáže zpracovat pouze jednu tabulku najednou, takže budete potřebovat tři příkazy:
DELETE FROM upklist
WHERE session_id = (SELECT session_id
FROM usession
WHERE delete_session_id IS NULL
AND user_id = (SELECT user_id
FROM users
WHERE REGEXP_LIKE(USER_NAME,
'awpeople', 'i')));
DELETE FROM projshar
WHERE session_id = (SELECT session_id
FROM usession
WHERE delete_session_id IS NULL
AND user_id = (SELECT user_id
FROM users
WHERE REGEXP_LIKE(USER_NAME,
'awpeople', 'i')));
DELETE FROM usession
WHERE session_id = (SELECT session_id
FROM usession
WHERE delete_session_id IS NULL
AND user_id = (SELECT user_id
FROM users
WHERE REGEXP_LIKE(USER_NAME,
'awpeople', 'i')));
Všimněte si, že protože vnitřní dotaz závisí na usersession
, měli byste z něj smazat poslední .
