仅从15分钟后选择

Question

I would likt to select text from chatlog which is max. 15 minutes old, but this doesn't work

What am i doing wrong?

My field "date" is 2013-01-04 22:50:53

 select user 
 from chatlog 
 WHERE date  >= DATE_SUB(CURDATE(),INTERVAL 15 MINUTE) 
   AND  room = '".$roomId."' 
   and user != 35 
   and event_id IS NULL

Did also try <= instead of >=

Answer 1

CURDATE only has a date component (not time). You need to use NOW() instead.

Answer 2

You need to use NOW() :

SELECT `user`
FROM chatlog
WHERE date > NOW() - INTERVAL 15 MINUTE
    AND room = '" . $roomId . "' 
    AND `user` != 35 
    AND event_id IS NULL

Answer 3

Try this:

SELECT user FROM chatlog 
     WHERE date  >= NOW() - INTERVAL 15 MINUTE
     AND  room = '".$roomId."' 
     AND user != 35
     AND event_id IS NULL
