Difference between usage of return $query->result() and return $query-row()

result() is working for single results, too, and you have nothing to change.

To make the difference clearer: use result() if you expect to get 0-n results, whereas n can be any number, use row() if you exactly know that you can only get 0-1 results (by limiting the query using $this->db->limit(...) for example) or in case that you are accessing unique data where you are absolutely sure that there is just one result.
