> select payment_id from transactions order by payment_id desc limit 1; This one is indeed instant! Less than 50ms. In my case I can't use it for max though because of the fact that payment_id can be null (which is an unfortunate design choice). The other variant however didn't become instant. I.e. I tried: select time from transactions where payment_id = 67 order by time asc limit 1; But this one is still really slow. Regards Express yourself instantly with MSN Messenger! MSN Messenger |
