Well, if you're using MySQL 4.1+, you're in luck. A subquery should help. SELECT ticker, HOUR(time) AS hour, price FROM pricedata WHERE time IN (SELECT MIN(time), MAX(time) FROM pricedata WHERE HOUR(time) = HOUR(pickatime) ) If you have an older version, simply split it up into two queries and use your middle/front end to handle the intermediate result -- Bob IQ2GI5SCP2 Things You Don't Hear Every Day, #'s 16 and 17: A professor: "It's all right if you come to class high."
