如何显示分组中的所有列

Question

我有两个表team和bobotteam ，然后我尝试这个查询：

SELECT team.id , bobotteam.teamfight/MAX(bobotteam.teamfight)
    FROM team
    INNER JOIN bobotteam on team.id = bobotteam.id

为什么数据只显示1个数据，即使我在bobotteam表中有两个数据。 图片

Answer 1

请试试这个：

SELECT team.id , bobotteam.teamfight/(select MAX(bobotteam.teamfight) from bobotteam)
FROM team
INNER JOIN bobotteam on team.id = bobotteam.id
