Re: GROUP BY, MIN() row ordering problems!
oh, i see. yes, you need to order the data first, probably with a subquery, like this :
SELECT *, MIN(r.time) FROM (select * from results as r order by r.time asc) AS r JOIN athletes AS a USING (athleteID) GROUP BY athleteID ORDER BY r.time ASC;
+-----------+----------+-------+----------+----------+------------+--------+------+---------+-------------+--------+-------------+------------+-----------+-----------+--------+------------+--------+-------------+
| athleteID | resultID | event | ageGroup | time | distHeight | record | wind | placing | competition | in_out | venue | date | nameFirst | nameLast | gender | DOB | clubID | MIN(r.time) |
+-----------+----------+-------+----------+----------+------------+--------+------+---------+-------------+--------+-------------+------------+-----------+-----------+--------+------------+--------+-------------+
| 3450 | 30 | 100m | SM | 00010.15 | 000000 | | 1.6 | 1 | Test Meet | Out | Auckland | 2008-01-01 | Gavin | LOVEGROVE | M | 1967-10-21 | 151 | 00010.15 |
| 822 | 26 | 100m | SM | 00010.20 | 000000 | | 1.1 | 1 | Battle | Out | Hamilton | 2008-02-01 | James | DOLPHIN | M | 1983-06-17 | 151 | 00010.20 |
| 825 | 27 | 100m | SM | 00010.56 | 000000 | | 1.1 | 1 | New Meet | Out | Auckland | 2008-01-01 | Chris | DONALDSON | M | 1975-05-26 | 151 | 00010.56 |
| 199 | 23 | 100m | SM | 00010.59 | 000000 | | 0.9 | 2 | Battle | Out | North Shore | 2008-01-02 | Craig | BEARDA | M | 1982-06-17 | 151 | 00010.59 |
+-----------+----------+-------+----------+----------+------------+--------+------+---------+-------------+--------+-------------+------------+-----------+-----------+--------+------------+--------+-------------+
Does that make more sense? (at least the 'time' col is the same as the 'MIN(r.time)' col now).
