SQL嵌套或相關查詢

Question

我正在嘗試計算針對具有特定變量的服務器數量相同的子查詢計數的服務器數量。我可以返回一個實體的資產總數，但是當我返回符合條件的資產總數時，它會給我的總數而不是我具體業務的數量。

SELECT DATEPART(week, GETDATE()) AS WEEK, bt.TranslatedParentBusiness AS [Parent Business], count(cars.ServerID) as [Count of Servers], 

(Select count(auth.serverID) from AuthTracking auth where [AUTH STATUS] like 'PASSED') 
FROM  ASSETS.dbo._CARS AS cars INNER JOIN 
       ASSETS.dbo.BU_Translation AS bt ON cars.CARS_SubBusiness = bt.[CARS Sub Business] 

GROUP BY bt.TranslatedParentBusiness  

Answer 1

SELECT 
    DATEPART(week, GETDATE()) AS WEEK, 
    bt.TranslatedParentBusiness AS [Parent Business], 
    count(cars.ServerID) as [Count of Servers], 
    count(CASE WHEN [AUTH STATUS] = 'PASSED' THEN auth.serverID END) 
FROM  ASSETS.dbo._CARS AS cars INNER JOIN 
       ASSETS.dbo.BU_Translation AS bt ON cars.CARS_SubBusiness = bt.[CARS Sub Business] 
GROUP BY bt.TranslatedParentBusiness
