How to optimize this query: SELECT col1, col2, MAX(col3) FROM Table WHERE col4>2 AND col5 = 2 GROUP BY col3 LIMIT 1;
The best that i figured out is to set the index on col3. I was unable to find out the working combination for multi-column indexing. Please advice. --------------------------------------------------------------------- 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?
