Question

Using the SalesOrderHeader and SalesTerritory tables, write a query to calculate the number of transactions and total monthly amount per territory for each of the states based on the Status field. Status values are: 1 = In process ; 2 = Approved ; 3 = Backordered ; 4 = Rejected ; 5 = Shipped ; 6 = Canceled The result table must contain the following fields:

月份：YYYY-MM 格式的月份
NameTerritory : 领土名称
TrProcess：处理中的交易（数量）
TrApproved：批准的交易（数量）
TrBackordered：逾期交易（数量）
TrRejected：被拒绝的交易（数量）
TrShipped：发送的交易（数量）
TrCanceled：交易取消（数量）
MntProcess：处理中的总量
MntApproved：已批准的总金额
MntBackordered：欠款总额
MntRejected：拒绝总金额
MntShipped：发送的总数量
MntCanceled：已取消的总金额

SELECT 
    FORMAT(A.ShipDate, 'yyyy-MM') as Mes,
    B.Name,
    (SELECT count(Status) FROM [dbo].[SalesOrderHeader] where Status = 1) as TrProcess,
    (SELECT count(Status) FROM [dbo].[SalesOrderHeader] where Status = 2) as TrApproved,
    (SELECT count(Status) FROM [dbo].[SalesOrderHeader] where Status = 3) as TrBackordered,
    (SELECT count(Status) FROM [dbo].[SalesOrderHeader] where Status = 4) as TrRejected,
    (SELECT count(Status) FROM [dbo].[SalesOrderHeader] where Status = 5) as TrShipped,
    (SELECT count(Status) FROM [dbo].[SalesOrderHeader] where Status = 6) as TrCanceled,
    (SELECT SUM(TotalDue) FROM [dbo].[SalesOrderHeader] where Status = 1) as MntProcess,
    (SELECT SUM(TotalDue) FROM [dbo].[SalesOrderHeader] where Status = 2) as MntApproved,
    (SELECT SUM(TotalDue) FROM [dbo].[SalesOrderHeader] where Status = 3) as MntBackordered,
    (SELECT SUM(TotalDue) FROM [dbo].[SalesOrderHeader] where Status = 4) as MntRejected,
    (SELECT SUM(TotalDue) FROM [dbo].[SalesOrderHeader] where Status = 5) as MntShipped,
    (SELECT SUM(TotalDue) FROM [dbo].[SalesOrderHeader] where Status = 6) as MntCanceled
FROM [dbo].[SalesOrderHeader] A
INNER JOIN [dbo].[SalesTerritory] B on A.TerritoryID = B.TerritoryID
GROUP BY FORMAT(A.ShipDate,'yyyy/MM')

我设置了此查询，但无法查询 return 金额。如果有人能帮助我，我将不胜感激。

您的逻辑有缺陷，子查询与主查询中的 branch/date 之间没有关联，因此它们合计了所有内容。使用条件聚合展示差异

SELECT 
    FORMAT(A.ShipDate, 'yyyy-MM') as mes,
    B.Name,
    (SELECT count(Status) FROM [sales].[SalesOrderHeader] where Status = 5) as TrProcess,
     sum(case when status = 5 then 1 else 0 end)  as trtprocesstrue

FROM [sales].[SalesOrderHeader] A
INNER JOIN [sales].[SalesTerritory] B on A.TerritoryID = B.TerritoryID
where b.name = 'northwest'
GROUP BY b.name,FORMAT(A.ShipDate, 'yyyy-MM') ;

mes        Name                                               TrProcess   trtprocesstrue
