Unable to jump to row 0

[jasondavis]

My code

function check_friend($userid, $friendid) {
    $sql = "SELECT userid FROM friend_friend
                WHERE userid='$userid'
                    AND friendid='$friendid'
					AND status='1'
                LIMIT 1";
    $result = executeQuery($sql);
    return mysql_result($result, 0) != 0;
} 

this line

    

return mysql_result($result, 0) != 0;
} 

gives me this error sometimes
Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 11 in /home/friend/public_html/config/functions.inc.php on line 1813

How can I fix this?

Perhaps you need to first check to see if any rows were returned? (If there were no matching rows for the query, then there would not be any row 0.)
