Question

尝试看看哪个球员获得了最多的进球。

Player_id
Goals.

我尝试了以下声明：

select player_id, sum(goals) as total
from matchstat
group by player_id
order by total desc limit 1;

但我得到错误：

SQL命令未正确结束。

有没有人看到查询的问题？

Oracle不支持限制条款。尝试

SELECT * 
FROM   (SELECT "player_id", 
               SUM("goals") AS total 
        FROM   matchstat 
        GROUP  BY "player_id" 
        ORDER  BY total DESC) a 
WHERE  ROWNUM <= 1

See a demo

无法让查询工作
