Not necessarily. It depends on the time defined for long_query_time. If you set it too high like 1000 then probably you won't see any query in the log.

ok but I meant if I set it to an optimize time that is a second is in real life there is actually an empty one?<br />
because im new to db and trying to optimize my database but its seem i keep having queries in the slow log file that are really short and simple<br />
such as SELECT and no INNER JOIN and so on <br />
(they are also examining really short rows)<br />
&nbsp;so i don't think there is a way to optimize them.<br />
and im not really sure i understand how cone they are there if only dealing with one row
