可以從SUM列進行計算嗎？

Question

我不確定這是否可能，但我一直在嘗試計算兩個SUM（CASE ...）的結果，以便能夠計算每個刷新周期的完成百分比。

這有點復雜...

SELECT RefreshCycle,

SUM(CASE WHEN RefreshStatus IN ('In Progress', 'Not Started', 'Not Due') and Status = 'Deployed' THEN 1 ELSE 0 END) + SUM(CASE WHEN RefreshStatus = 'Completed' and Status NOT IN ('Deployed') THEN 1 ELSE 0 END)  as 'Total', 
SUM(CASE WHEN RefreshStatus = 'Completed' and Status NOT IN ('Deployed') THEN 1 ELSE 0 END) as 'Completed', 
SUM(CASE WHEN RefreshStatus = 'In Progress' and Status = 'Deployed' THEN 1 ELSE 0 END ) as 'In Progress', 
SUM(CASE WHEN RefreshStatus = 'Not Started' and Status = 'Deployed' THEN 1 ELSE 0 END) as 'Not Started', 
SUM(CASE WHEN RefreshStatus = 'Not Due' and Status = 'Deployed' THEN 1 ELSE 0 END)  as 'Not Due', 
SUM(CASE WHEN RefreshStatus = 'Not Eligible' and Status = 'Deployed' THEN 1 ELSE 0 END)  as 'Not Eligible'

--('Total') / ('Completed') *100.00 as 'Percentage'

--SUM(CASE WHEN RefreshStatus IN ('In Progress', 'Not Started', 'Not Due') and Status = 'Deployed' THEN 1 ELSE 0 END) + SUM(CASE WHEN RefreshStatus = 'Completed' and Status NOT IN ('Deployed') THEN 1 ELSE 0 END) / SUM(CASE WHEN RefreshStatus = 'Completed' and Status NOT IN ('Deployed') THEN 1 END)* 100.00 as 'Completed' 

FROM Hardware_Inventory 

WHERE Status NOT IN ('In Stock', 'Parts') 
and Manufacturer NOT IN ('Apple') 
and AssetType NOT IN ('Monitor','Docking Station','Optical Drive','Other', 'Projector', 'Scanner/Printer', 'BlackBerry', 'Server') 
GROUP BY RefreshCycle
ORDER BY RefreshCycle asc;

這給我這個結果

由於我在互聯網上找不到真正的類似查詢，因此我對此一無所知。 誰能指出我正確的方向？

試試這個方法

select total + completed sumOfSums1
from (
