Keeping statistics....

[eluser]codelearn[/eluser]
Quick question:

Is there a way to write that update query with Active Record... something like:

$this->db->where('rest_id',$IRIresults->id);
$this->db->where('date', $todays_date);
$this->db->set('hits','hits+1'); <--**This does not work, obviously**
$this->db->update('rest_stats');
