平均最大MYSQL

我想选择2-3名球员的平均高分，但我不知道该怎么做

桌上比赛有id、球员、分数

我想通过id获得每个指定玩家的最高分数，然后计算这些返回分数的平均值

任何帮助都将不胜感激

以下查询将返回每位玩家的最高分数：

CREATE TABLE Match(Id integer PRIMARY KEY, score integer);

/* Create few records in this table */
INSERT INTO Match VALUES(1,'10');
INSERT INTO Match VALUES(2,'20');
INSERT INTO Match VALUES(3,'60');
INSERT INTO Match VALUES(4,'100');
INSERT INTO Match VALUES(5,'80');
COMMIT;


select m.*,
       (select sum(score)
        from (select score
              from Match s
              where s.id = s.id
              order by score desc
              limit 3
             ) s2
       ) as summax3
from Match m

SELECT *
FROM
    (
    SELECT `match`.id, `match`.score
    FROM `match`
    ORDER BY score DESC
    LIMIT 3
) AS high_scores
GROUP BY id
ORDER BY score DESC

要获得平均值：

SELECT AVG(score) AS average
FROM
    (
    SELECT `match`.id, `match`.score
    FROM `match`
    ORDER BY score DESC
    LIMIT 3
) AS high_scores
