SQL查詢：如何將計數函數結果組合到選擇查詢中？

Question

select distinct Franchise.FranchiseName, Franchise.Initials, Franchise.StoreNo, AccountCancellation_Process.Store_Num 
FROM FranchiseData
INNER JOIN AccountCancellation_Process
on FranchiseData.StoreNo = AccountCancellation_Process.Store_Num

select count(*) from AccountCancellation_Process where Store_Num = '1234' 
select count(*) from AccountCancellation_Process where Store_Num = '1234' and Progress is not null

我想將AccountCancellation_Process的count（*）合並到上面的內部連接語句中，以便查詢將給我結果，FranchiseName，Initials，Franchise表中的StoreNo和AccountCancellation_Process中的Store_Num的結果與總記錄和不帶Progress列的總記錄一起空值。

如何將查詢結果與計數功能結果結合在一起？

謝謝。

Answer 1

這樣，我想就是您想要的。 我創建了兩個與表值相關的子查詢，以基於內部聯接表中存儲的數字獲取數據。 然后我根據商店編號加入他們。 這樣，獨特的將工作。 但是，您也可以只使用相關的子查詢就可以對選擇部分進行計數。 我擔心區別可能不會起作用。

SELECT DISTINCT Franchise.FranchiseName, Franchise.Initials, Franchise.StoreNo, acp.Store_Num, total_count.Total_Count, progress_count.Progress_Count
FROM FranchiseData
     INNER JOIN AccountCancellation_Process AS acp ON (FranchiseData.StoreNo = acp.Store_Num)
     INNER JOIN (SELECT Store_Num, COUNT(*) AS Total_Count FROM AccountCancellation_Process WHERE Store_Num = acp.Store_Num) AS total_count ON (acp.Store_Num = total_count.Store_Num)
     INNER JOIN (SELECT Store_Num, COUNT(*) AS Progress_Count FROM AccountCancellation_Process WHERE Store_Num = acp.Store_Num AND Progress IS NOT NULL) AS progress_count ON (acp.Store_Num = progress_count.Store_Num)

別名count（*）然后使用Sum（alias）
