Active records question, join and two id's how to get each id??

[eluser]123wesweat[/eluser]

Code:

$this->db->from('tableA');
                $this->db->join('tableA', 'tableA.id = tableB.nameID');
                $this->db->where('user_id', $user_id);
                return $this->db->get();

But i have an field name id in both tables, how do i get both of this id's??

At the moment i have

Code:

$res = $this->db_model->get_profile($user_id)->result

$res->id just gives the id of tableA.

How do i get tableB.id???

By definition grabbing everything instead of only what you need is not optimal, no
