Php 如何编辑此mssql查询？

下面的查询与我的部族排名php脚本关联

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

我想为MannerPoint添加第二条规则，作为忠诚度的补充。 因此，它将显示方式和忠诚度点数，并按两者排序

例如，如果氏族拥有10000个忠诚和100种方式，那么它的排名将高于20000个忠诚和50种方式

我试了几次，但失败了。如果有人愿意帮助我，我将不胜感激

编辑：我试过： 选择前100名IDNum、IDName、Nation，从USERDATA中选择SUMLoyaltyPoint，其中USERDATA.Knights=Knights.IDNum和USERDATA.Authority IN1，2为氏族忠诚，从USERDATA中选择SumAnnerPoint，其中USERDATA.Knights=Knights.IDNum和USERDATA

但它根本不显示。

您可以使用外部应用将忠诚点和礼貌点相加：

select top 100
    k.IDNum, 
    k.IDName, 
    k.Nation, 
    u.ClanLoyalty,
    u.ClanManner 
from KNIGHTS as k
    outer apply (
        select
            sum(u.LoyaltyPoint) as ClanLoyalty,
            sum(u.MannerPoint) as ClanManner
        from USERDATA as u
        where u.Knights = k.IDNum and u.Authority in (1, 2)
    ) as u
order by u.ClanManner desc, u.ClanLoyalty desc

或简单子查询：

select top 100
    k.IDNum, 
    k.IDName, 
    k.Nation, 
    u.ClanLoyalty,
    u.ClanManner
from KNIGHTS as k
    left outer join (
        select
            u.Knights,
            sum(u.LoyaltyPoint) as ClanLoyalty,
            sum(u.MannerPoint) as ClanManner
        from USERDATA as u
        where u.Authority in (1, 2)
        group by u.Knights
    ) as u on u.Knights = k.IDNum
order by u.ClanManner desc, u.ClanLoyalty desc

不知道您想如何订购记录，如果您想按ClanWay和Clan忠诚度之和订购，您可以这样做：

order by isnull(u.ClanManner, 0) + isnull(u.ClanLoyalty, 0) desc

这：

有一个语法问题，其中有一个额外的括号，应该是：

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`

首先，您需要指定方式点的存储位置。它们在用户数据中的位置与忠诚度点相同。在主select语句中，为方式点添加另一个返回列，并将其包含在您的订单中。例如，select[existingColumn]，选择方式作为MannerPoint from。。。哪里按MannerPoint desc排序，宗族忠诚度desc选择前100名IDNum，IDName，Nation，从USERDATA中选择SUMLoyaltyPoint，其中USERDATA.Knights=Knights.IDNum和USERDATA.Authority IN1，2作为宗族忠诚度，从USERDATA中选择SumAnnerPoint，其中USERDATA.Knights=Knights.IDNum和USERDATA.Authority IN1，2作为骑士骑士团的人物点忠诚描述，人物点描述是这样的吗？这完全正确吗？是的，我想这是正确的

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`
