需要包裹查詢計數結果

Question

我有這個疑問：

SELECT 
[QUERY1].[py], 
[QUERY1].[al], 
[QUERY1].[ga], 
[QUERY1].[sy], 
[QUERY1].[pl] 
FROM [tab-Sample] as QUERY1, [tab-Sample] 
WHERE [tab-Sample].[py] = [QUERY1].[py] AND 
[tab-Sample].[al] <> [QUERY1].[al] 

我想編寫僅僅指剛計數這一結果的查詢，我無法找到要插入COUNT（*）也用Over（）嘗試，但我無法管理這個。

將所有內容都作爲FROM中的子選項進行包裝。請確保您將其命名（Total）。

COUNT (*) AS Amount FROM 
(
SELECT 
[QUERY1].[py], 
[QUERY1].[al], 
[QUERY1].[ga], 
[QUERY1].[sy], 
[QUERY1].[pl] 
FROM [tab-Sample] as QUERY1, [tab-Sample] 
WHERE [tab-Sample].[py] = [QUERY1].[py] AND 
[tab-Sample].[al] <> [QUERY1].[al] 
) Total
