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-

To add on to what Alisson said you could check to see if a row is returned.

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

if ($query->num_rows() > 0)
{
    $row = $query->row(); 
    return $row->campaign_id;
}

return null; // or whatever value you want to return for no rows found
