以下のクエリは、私のクラン ランキング php スクリプトに関連付けられています。

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

MannerPointLoyalty の追加として2 番目のルールを追加したいと思います。そのため、マナー ポイントとロイヤリティ ポイントの両方が表示され、両方で並べ替えられます。

たとえば、クランの忠誠度が 10000 でマナーが 100 の場合、忠誠度が 20000 でマナーが 50 しかない場合よりもランキングが高くなります。

いくつか試しましたが失敗しました。誰かが私を助けてくれると本当にありがたいです.

編集：私はそれを試しました： 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

しかし、それはまったく表示されません。

LoyaltyPoint両方を合計し、 MannerPointouter apply を使用できます。

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

または単純なサブクエリ:

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

ClanManner と ClanLoyalty の合計で並べ替える場合は、次のようにします。

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

これ：

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`

余分な括弧が含まれる構文の問題があり、次のようにする必要があります。

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`
