I am returning a set of records for list_data, but want to add a default value not stored in the table.
$id = empty($id) ? 0 : $id;
$results = self::model()->findAllBySql('select id, menu_title from sales where id <> :p1 order by menu_title', array(':p1' => $id));
$results = array(0=>'No Parent') + $results; // not working
return $results;
