無法讓查詢起作用

Question

嘗試查看哪個玩家獲得了最多的目標。

Player_id 
Goals. 

我嘗試了以下聲明：

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

，但我得到的錯誤：

SQL command not properly ended.

有誰看到在查詢的問題？

Answer 1

Oracle不支持限制條款。嘗試

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