delete(); /** * On session drivers other than mysql doctrine would now perform three queries * regardless of how many users, emails and phonenumbers there are * * the queries would look something like: * DELETE FROM entity WHERE entity.id IN (1,2,3, ... ,15) * DELETE FROM phonenumber WHERE phonenumber.id IN (4,6,7,8) * DELETE FROM email WHERE email.id IN (1,2, ... ,10) * * On mysql doctrine is EVEN SMARTER! Now it would perform only one query! * the query would look like: * DELETE entity, email, phonenumber FROM entity * LEFT JOIN phonenumber ON entity.id = phonenumber.entity_id, email * WHERE (entity.email_id = email.id) && (entity.id IN(4, 5, 6, 7, 8, 9, 10, 11)) && (entity.type = 0) */ ?>
