Hi Darryle,
Your result was:
+-----------+-------+---------+
| member_id | name | head_id |
+-----------+-------+---------+
| 2 | Ann | 1 |
| 3 | David | NULL |
| 1 | Elim | NULL |
| 5 | Jane | 3 |
| 4 | John | 3 |
+-----------+-------+---------+
which not groups correctly. Seems it's a hard query.

Subject: Re: Hard? query to with group order by group head's name

Hi Elim,
     I didn't test it out but it sounds like you want to do this "
SELECT * FROM group_members GROUP BY head_id, member_id ORDER BY name
ASC ".
