查询不返回任何内容？ [复制]

Question

此查询在我的氏族 php 排名脚本中正确显示。

SELECT TOP 100 
  IDNum, 
  IDName, 
  Nation, 
  (SELECT SUM(LoyaltyPoint) 
   FROM USERDATA 
   WHERE USERDATA.Knights = KNIGHTS.IDNum 
     AND USERDATA.Authority IN(1, 2)) as ClanLoyalty 
FROM KNIGHTS 
ORDER BY ClanLoyalty DESC

但我想在LoyaltyPoint 之上为MannerPoint 添加第二条规则。

SELECT TOP 100
  IDNum,
  IDName,
  Nation,
  (SELECT SUM(LoyaltyPoint)
    FROM USERDATA
    WHERE USERDATA.Knights = KNIGHTS.IDNum
        AND USERDATA.Authority IN(1, 2)) as ClanLoyalty,
  (SELECT SUM(MannerPoint) 
   FROM USERDATA
   WHERE USERDATA.Knights = KNIGHTS.IDNum
       AND USERDATA.Authority IN(1, 2)) ) as MannerPoint
FROM KNIGHTS
ORDER BY ClanLoyalty DESC, MannerPoint DESC

但这不起作用并且不显示。

我使用 MSSQL 2005

Answer 1

你这里多了一个括号；

AND USERDATA.Authority IN(1, 2)) ) as MannerPoint

去掉多余括号的调整代码：

AND USERDATA.Authority IN(1, 2) ) as MannerPoint
