mysql - 我的 MySQL 查询如何给出所有游戏的排名只给出每个玩家顶级游戏的排名？

Question

SELECT 
1+(SELECT count(*) from games a WHERE a.score > g.score) as rank,
score, p.leaderboard_initials, p.operating_system
FROM games g
inner join players p on (p.google_id = g.google_id)
ORDER BY score DESC
LIMIT 0, 100;

返回一个排行榜，其中包含玩家的每场比赛。

我需要返回一个排行榜，其中只列出了每个玩家的最佳得分游戏。所以 44rhh 仍将排在首位，其次是 DMC，但 BMO 将排在第三位。

我知道解决方案应该很简单，但我就是想不出该怎么做!

您可以按 leaderboard_initials 选择最高分组

您可以按 leaderboard_initials 选择最高分组

set @rank=0;
select (@rank:=@rank+1) rank , leaderboard_initials, max(score)  max_score  
from  (
    SELECT 
    1+(SELECT count(*) 
    from games a WHERE a.score > g.score) as rank,
    score, p.leaderboard_initials, p.operating_system
    FROM games g
    inner join players p on (p.google_id = g.google_id)
    ORDER BY score DESC
    LIMIT 0, 100;
) t  
group by leaderboard_initials 
order by max_score DESC
