Including values NOT FOUND in MySQL query results

Question

I have the following MySQL tables:

tbl_pet_owners:

+----+--------+----------+--------+--------------+
| id | name   | pet      | city   | date_adopted |
         


        

Answer 1

Then perform a RIGHT JOIN instead of LEFT JOIN saying

RIGHT JOIN tbl_pet_types types ON owners.pet = types.pet

In case you want outer joined result for both table (which not sure off), you can then consider doing a FULL JOIN by mixing right and left join
