Hi there, I do have a user table with 38000 records. Now I would like to count the female and male users. This query:
SELECT sex, count(*) AS c FROM user GROUP BY sex works, but takes 0.8 s So I don't think an index would do some good. There are only two values 1, and 2 The column type is tynyint(1) and contains 50 % "1" and 50% "2" values explains says: using temporary on 38000 rows So is there a way to do this faster. Choosing a different column type ore similar stuff? Thanx for any help, andy --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
