T-SQL GROUP BY與Count（）和計算不正確分組和計數

Question

我編寫代碼的目的是為了對“ CurrentStatus”進行分組，將“ IN”和“ OUT”的記錄數除以“ currentstatus”，然后將“ OUT”記錄除以特定“ CurrentStatus”的記錄總數根據“ CurrentStatus”（IN + OUT）的總數記錄獲得“ CurrentStatus”中“ OUT”的百分比。下面是代碼片段。

 SELECT DISTINCT convert(date, Getdate(), 1) [Date], channel, CurrentStatus, (select count(number) from dbo.vw_AP where channel = 'C' AND [In/Out of Tolerance] = 'in') [In], (select count(number) from dbo.vw_AP where channel = 'C' AND [In/Out of Tolerance] = 'out') [Out], count(number) [Total], convert(Decimal(18,2), (1.0 * (select count(number) from dbo.vw_AgedPipeline where channel = 'C' AND [In/Out of Tolerance] = 'out') / count(number))) [OOTP] FROM [dbo].[vw_AgedPipeline] WHERE Channel = 'C' GROUP BY CurrentStatus, channel order by Channel, CurrentStatus 

該代碼返回的結果“ IN”是按通道的“ IN”總數（而不是CurrentStatus），“ OUT”是按通道的“ OUT”總數，“ TOTAL”是按“ CurrentStatus”。我希望代碼按CurrentStatus的“ IN”，“ OUT”和“ TOTAL”分組。有人可以幫忙嗎？

;WITH CTE AS 
(SELECT  
     convert(date, Getdate(), 1) [Date]
    ,v.channel
    ,v.CurrentStatus
    ,count(CASE WHEN  A.[In/Out of Tolerance] = 'in'  THEN 1 ELSE NULL END) [In]
    ,count(CASE WHEN  A.[In/Out of Tolerance] = 'out' THEN 1 ELSE NULL END) [Out]
    ,count(v.number) [Total]
FROM [dbo].[vw_AgedPipeline] V
INNER JOIN dbo.vw_AP A ON v.Channel = A.Channel
WHERE V.Channel = 'C'
GROUP BY v.channel,v.CurrentStatus
order by v.channel,v.CurrentStatus
)
SELECT [Date]
       ,channel
       ,CurrentStatus
       ,[In]
       ,[Out]
       ,[Total]
       ,convert(Decimal(18,2),  (1.0 * [Out]) / ([Total] * 1.0)) [OOTP]
