获取用户在mySql数据库中的位置

Question

我试图在basketballScore的排行榜中获得特定用户的位置。数据库中只有一个表。 这是mySQL中数据库的图像

我想它会是这样的：

declare module 'recase'

Answer 1

您需要select userID, SUM(score) as basketballScore from user group by userID order by basketballScore desc 子句：

basketballScore

另请注意，我在order by子句中重用了别名set @rank := 0; select @rank := @rank + 1 as rank, userID, SUM(score) as basketballScore from user group by userID order by basketballScore desc 。

如果您需要创建排名，可以使用用户变量：

{{1}}

Answer 2

您可以通过以下方式获取特定用户的排名：

select 1 + count(*) as rank
from user u
where u.basketballScore > (select u2.basketballScore from user u2 where u2.userId = @userId);
