您可以使用自連接找出遊戲的正確球隊ID的具有最高得分

SELECT s.* 
FROM scores s 
JOIN (
SELECT MAX(score) score, id_game 
FROM scores 
GROUP BY id_game) ss USING(score ,id_game)

'選擇A.id_game，A.id_team從分數甲WINNING_TEAM ，（選擇最大值（評分）作爲max，id_game from score group by id_game ）B 其中A.id_game = B.id_game and A.score = B.max' – user1950896
