How to Force Code Igniter to NOT to excape queries?

[eluser]Sheikh Aman Alam[/eluser]
Got it working.
used the join() method and now the code is like-

$this->db->select(`comment`.`commenttext`, `comment`.`cd`, `user`.`username`);
$this->db->from('comment');
$this->db->join('user','user.userid=comment.userid');
$this->db->where($criterea);
$resultSet= $this->db->get()

thanks a lot for giving ideas guys..
