I would add a second column to that admin_lastping KEY KEY `admin_lastping` (`admin_lastping`, `admin_id`) Since you are using both columns in your where clause, they both need to be specified /in the same/ index for and index to be used. Otherwise, some random index might be used. But you will get the best performance if both are listed in the same index. -- Jim Lucas "Some men are born to greatness, some achieve greatness, and some have greatness thrust upon them."
