sql - 列“a.p_id”在选择列表中无效，因为它既不包含在聚合函数中，也不包含在 GROUP BY 子句中

Question

select max(a.totalgoal)as 'MAXIMUM goles',p_id
from 
(select playerperform.p_id, SUM (playerperform.score)as totalgoal from playerperform  
Group by p_id)as a

Answer 1

在 SQL Server 中，您可以为此使用该RANK()函数：

SELECT *
from (select playerperform.p_id, SUM (playerperform.score)as totalgoal, RANK() OVER(ORDER BY SUM(playerperform.score)DESC) Rnk
      from playerperform  
      Group by p_id
      )as a
WHERE Rnk = 1
