Question

我遇到了如何加入子选择语句的问题。

打算检索父/子层次结构中链接的所有销售额的总和。每一行应显示层次结构中总销售额的总和，而不是唯一的子销售额

我可以轻松地分别获得所需的结果，但试图找出如何在单个查询中获取此数据。

预期结果：

AccountID   AccountName       REPLOGIN     TL_AccountID   TL_AccountName     SumGross
123456      Child Company A   Salesrep A   123654         Parent Company X   1500
123456      Child Company B   Salesrep C   123654         Parent Company X   1500

下面的SQL。子选择结果必须与TL_AccountID：

连接

SELECT
    dbo.Account.AccountID,
    dbo.Account.AccountName,
    dbo_Rep_Employee.Login AS REPLOGIN,
    TL_Account.AccountID AS TL_AccountID, 
    TL_Account.AccountName AS TL_AccountName, 
    TL_Address.Country AS TL_Country,

(SELECT SUM(Orders.GrossAmount) AS SumGross

FROM    Position 
                INNER JOIN Account ON Position.PositionID = Account.PositionID 
                INNER JOIN Employee ON Position.EmployeeID = Employee.EmployeeID 
                INNER JOIN Address ON Account.AddressID = Address.AddressID 
                INNER JOIN Account AS TL_Account ON Account.TopPurchasingAccountID = TL_Account.AccountID 
                INNER JOIN Address AS TL_Address ON TL_Account.AddressID = TL_Address.AddressID

                LEFT OUTER JOIN PriceList AS PriceList ON Orders.PriceListID = PriceList.PriceListID

WHERE               
                (Orders.SalesChannel LIKE '%NL.%' OR Orders.SalesChannel LIKE '%.nl%') AND 
                (Orders.DateDeleted IS NULL) AND 
                (Orders.OrderDate > DATEADD(MM, - 13, CONVERT(DATE, DATEADD(mm, DATEDIFF(MM, 0, DATEADD(DD, - 3, CURRENT_TIMESTAMP)) + 1, 0)))) AND

您可以尝试使用SQL用户定义函数，它将接受输入参数并返回表值结果集，其中包含可以连接到上述结果集的查询下半部分的必需值

JOIN子SELECT语句
