试试这个：
SELECT gamers.*
FROM gamers
INNER JOIN
(SELECT
max(score) as maxscore,
gameid from gamers
GROUP BY gameid) AS b
ON (b.gameid = gamers.gameid AND b.maxscore=gamers.score) ;
ORDER BY score DESC, gameid;
这将输出：
+---------+--------+-------+
| gamerid | gameid | score |
+---------+--------+-------+
| 4 | 1 | 90 |
| 5 | 2 | 40 |
| 8 | 3 | 30 |
+---------+--------+-------+
3 rows in set (0.00 sec)
您可以做的另一种选择是创建一个临时表或视图（如果您不喜欢子查询）。
create temporary table games_score (
SELECT max(score) as maxscore, gameid FROM gamers GROUP BY gameid
);
然后：
SELECT gamers.*
FROM gamers
INNER JOIN games_score AS b ON (b.gameid = gamers.gameid AND b.maxscore=gamers.score)
ORDER BY score DESC, gameid;
或视图：
create or replace view games_score AS
SELECT max(score) as maxscore, gameid FROM gamers GROUP BY gameid;
然后：
SELECT gamers.*
FROM gamers
INNER JOIN games_score AS b ON (b.gameid = gamers.gameid AND b.maxscore=gamers.score)
ORDER BY score DESC, gameid;
