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- gt db- gt get     ret    query- gt result    return  ret 0 - gt campaign id    Is there a CodeIgniter function to return the first row  something like  query- gt row     Or even better would be the ability to  if there was only one row  to just use the query object directly   e g   query- gt campaign id

To make the code clear that you are intending to get the first row, CodeIgniter now allows you to use:

if ($query->num_rows() > 0) {
    return $query->first_row();
}

To retrieve the first row.
