How to optimize select of random record in DB ?

I made this code to pick a random record from a changeable number of records in a given table. I'm just curious if any of the more awake coders out there can see a way to optimize this for better performance, since there's several other DB queries on the same page. $records = mysql_query("SELECT COUNT(*) AS count FROM persons") or die('Unable to get record count<br>'.mysql_error()); $totalcount = mysql_result($records,0) - 1; $rndrecord = rand(0,$totalcount); $personquery = mysql_query("SELECT personID FROM persons LIMIT $rndrecord,1") or die('Unable to get random record<br>'.mysql_error()); $personID = mysql_result($personquery,0); -- Rene Brehmer aka Metalbunny If your life was a dream, would you wake up from a nightmare, dripping of sweat, hoping it was over?
