Question

在我的表中，我有5列5行，现在我只需要添加3行的AmountPaid列，并希望存储在另一个表中。这3行包含唯一代码并记录到这个唯一代码我希望将这个总数加入新表。

我尝试了这段代码，但没有按照我的方式工作。

SELECT InvoiceNo, InvoiceDate, SalesPerson(SELECT SalesPerson FROM 
SalesDepartment WHERE SalesDepartment.SalesPersonId=Invoice.SalesPerson) 
AS SalesPerson, Customer, OrderNumber, GrandTotal, 

AmountPaid(SELECT AmountPaid FROM Payment WHERE 
Payment.InvoiceNo=Invoice.InvoiceNo) AS AmountPaid

FROM Invoice;

如果我删除最后一个AmountPaid列，则此代码正常工作。但是我需要添加一个表的付费金额并将其存储在另一个表列中。如何完成这项任务？

希望这有帮助。

子查询：

SELECT InvoiceNo,
       InvoiceDate,
       (SELECT SalesPerson FROM SalesDepartment WHERE SalesDepartment.SalesPersonId=Invoice.SalesPerson) AS SalesPerson,
       Customer,
       OrderNumber,
       GrandTotal,
       (SELECT SUM(AmountPaid) FROM Payment WHERE Payment.InvoiceNo=Invoice.InvoiceNo) AS totalAmountPaid
FROM Invoice;

Equijion：

SELECT InvoiceNo, 
       InvoiceDate,
       SalesPerson,
       Customer,
       OrderNumber,
       GrandTotal,
       SUM(AmountPaid) AS totalAmountPaid
FROM Invoice 
    INNER JOIN SalesDepartment ON SalesDepartment.SalesPersonId=Invoice.SalesPerson
    INNER JOIN Payment ON Payment.InvoiceNo=Invoice.InvoiceNo
GROUP BY InvoiceNo

在MS Access中添加一个表到另一个表时出错？
