est-il possible de calculer à partir des colonnes SUM?

Question

Je ne sais pas si cela est encore possible, mais j'ai essayé de calculer le résultat de deux SUM (CASE ... Résultats pour être en mesure de calculer le pourcentage d'achèvement pour chaque cycle de rafraîchissement.

son un peu compliqué ...

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; 

qui me reçoit ce résultat

2021/22   421   0   0   4  417 32 

je reçois un peu perdu dans ce depuis que je ne suis pas vraiment trouver requête similaire sur internet. Est-ce que quelqu'un peut-il me montrer la bonne direction?
