帶有Count（）和計算的T-SQL GROUP BY沒有正確分組和計數

Question

我編寫了代碼，目的是在「CurrentStatus」中進行分組，計算「currentstatus」記錄數爲「IN」和「OUT」 「，然後用」CurrentStatus「的總數記錄（IN + OUT）將」OUT「記錄除以特定」CurrentStatus「的記錄總數，以獲得」CurrentStatus「中的」OUT「的百分比。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

這段代碼帶回的「IN」的結果是通道的「IN」總數（而不是CurrentStatus），「OUT」是按通道「OUT」的總數，「TOTAL」是通過「CurrentStatus」的總數。我希望代碼按「IN」，「OUT」和「TOTAL」按CurrentStatus進行分組。誰能幫忙？

;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
