CodeIgniter - return only one row?

Question

At the moment if I am doing a query on the database that should only return one row, using:

...query stuff...
$query = $this->db->get();
$ret = $query-

You've just answered your own question :) You can do something like this:

$query = $this->db->get();
$ret = $query->row();
return $ret->campaign_id;
