$this->db->lastquery() not working

[eluser]D-dawg[/eluser]
There are different, but an update would look like:

Code:

function SetMarker($data, $id)
  {
    $this->db->set($data);
    if($id != 'null')
    {  $this->db->where('id', $id);
       $this->db->update('markers'); }
    else
    { $this->db->insert('markers');
    $data['id'] = $this->db->insert_id();}
    return $data;
  }

I know they work since the job gets done, still lastquery returns nothing. Is there another way with codeigniter or phpmyadmin I can view the entire last query?
