如何在SQL Server中查詢獲取客戶帳戶狀態？

我有這些表在我的數據庫：如何在SQL Server中查詢獲取客戶帳戶狀態？

*custmrsTble: (custID: PK,Int) - (Name: varchar(20)) 
============= 
custID  Name 
________________ 
1   Sam 
2   Tom 

ProductsTble: (prodID: PK,Int) - (prodName: varchar(20)) - (soldPrice: money) 
=========== 
prodID prodName soldPrice 
____________________________ 
1  Biscuits 20 
2  Butter  30 
3  Milk  10 

OrdersTbl: (orderID: PK,Int) - (orderDate: smallDateTime) - (custID: FK,Int) 
========== 
orderID orderDate custID 
____________________________ 
1   2013/4/2  1 
2   2013/4/2  2 
3   2013/4/3  1 
OrderDetails: (orderDetailsID : PK,Int)- (orderID: FK,Int) - (prodID: FK,Int) - (qntty: int) 
============= 
orderDetailsID orderID prodID qntty 
_______________________________________ 
1     1  1  2 
2     1  2  1 
3     1  3  2 
4     2  1  5 
5     3  1  1 
CashMoventsTble: (cashID : PK,Int)- (orderID: FK,Int) - (cashDate : smallDateTime) - (cashValue money) 
================ 
cashID orderID cashDate cashValue 
_____________________________________ 
1  1  2013/4/2 30 
2  2  2013/4/2 100 
3  1  2013/4/5 20 
4

所以，我想查詢將返回類似這樣的客戶狀態：

Name TotalPurchase  TotalPayments  
_______________________________________ 
Sam  110    50 
Tom  100    100

TotalPurchase = SUM（qntty）* soldPrice ---- >所有購買的每個客戶
TotalPayments =總額（cashValue）----->每個客戶的所有付款

但不知道如何做到這一點。所以請幫助我實現這一點。謝謝。

您需要爲集合函數使用「group by」子句。 – OldProgrammer 2013-05-02 12:55:17

OldProgrammer：當我這樣做時，它會向我展示每件產品，而我需要的是摘要而不是細節，正如我之前提到的 – 2013-05-02 13:01:31

SELECT c.Name 
    ,TotalPurchase = (
     SELECT SUM(p.soldPrice * d.qntty) 
     FROM OrderDetails d 
     INNER JOIN OrdersTbl o 
      ON d.orderID = o.orderID 
     INNER JOIN ProductsTbl p 
      ON p.prodID = d.prodID 
     WHERE o.custID = c.custID) 
    ,TotalPayments = (
     SELECT SUM(cm.cashValue) 
     FROM CashMoventsTble cm 
     INNER JOIN OrdersTbl o 
      ON o.orderID = cm.orderID 
     WHERE o.custID = c.custID) 
FROM custmrsTble c
