将复杂的算术公式应用于表SQL中的所有字段

Question

我对此请求有疑问：

SELECT 
    CASE WHEN ApNumber=0 THEN 0 
        WHEN ApNumber=1 THEN 100 
        WHEN ApNumber=2 THEN 250 
        WHEN ApNumber=3 THEN 500 
        WHEN ApNumber=4 THEN 750 
        WHEN ApNumber<=5 THEN 1000 END AS ApPoint,

    FactionInfo.FactionUUID


FROM
    (
        SELECT COUNT(isAP) AS ApNumber
        FROM ClaimInfo 
        WHERE FactionOwnerUUID =FactionInfo.FactionUUID
    )f0,

    FactionInfo

问题在于

FactionInfo.FactionUUID

WHERE FactionOwnerUUID =FactionInfo.FactionUUID

中的

产生未知列错误。

问题是我想要执行位于FactionInfo中的所有行的select中的所有计算。 建议？

最终请求应该给我：

FactionUUID - ApPoint
----------------------
FactionUUIDName 250
FactionUUIDOtherName 750

你似乎想要：

SELECT (CASE WHEN COUNT(isAP) = 0 THEN 0 -- this will never happen
             WHEN COUNT(isAP) = 1 THEN 100 
             WHEN COUNT(isAP) = 2 THEN 250 
             WHEN COUNT(isAP) = 3 THEN 500 
             WHEN COUNT(isAP) = 4 THEN 750 
             ELSE 1000
        END) AS ApPoint,
       ci.FactionOwnerUUID
FROM ClaimInfo ci
GROUP BY ci.FactionOwnerUUID;
