如何在sql server中获取此报告的查询？

Question

我有这个sql数据库

我希望显示以下数据：

注意：

  

总销售额=总和（ProductsTbl.SalePrice *   OrderDetailsTbl.SoldQuantity）

     

折扣=总和（ProductsTbl.SalePrice * OrderDetailsTbl.SoldQuantity）   * DiscountRatesTbl.DiscountRate / 100

     

支付= SUM（isnull（CashMovementTbl.CashMovementValue，00.00）

那么如何在SQL Server中进行查询以显示这样的数据。

感谢您的帮助。

我尝试了这个查询，但未能获得折扣：

SELECT  c.CustName as 'Customer' ,

Total Sales= ( SELECT SUM(p.SalePrice * d.SoldQuantity) FROM OrderDetailsTbl d 
INNER JOIN  OrdersTbl o ON d.orderID = o.orderID INNER JOIN  ProductsTbl p ON p.ProductID = d.ProductID
WHERE o.CustomerID = c.CustomerID ) ,

Discounts= (Select isnull(sum(p.SalePrice * d.SoldQuantity)* dr.DiscountRate/100),00.00 FROM OrderDetailsTbl d 
INNER JOIN  OrdersTbl o ON d.orderID = o.orderID INNER JOIN  ProductsTbl p ON p.ProductID = 
d.ProductID inner join DiscountRatesTbl dr on dr.orderID = o.orderID WHERE o.CustomerID = c.CustomerID ) ,

Payed=  ( SELECT  SUM(isnull(cm.CashMovementValue,00.00)) FROM CashMovementTbl cm
INNER JOIN OrdersTbl o  ON o.orderID = cm.orderID WHERE  o.CustomerID = c.CustomerID)

FROM    CustomersTbl c
where ( SELECT SUM(p.SalePrice * d.SoldQuantity) FROM OrderDetailsTbl d 
INNER JOIN  OrdersTbl o ON d.orderID = o.orderID INNER JOIN  ProductsTbl p ON p.ProductID = 
d.ProductID WHERE o.CustomerID = c.CustomerID ) is not null 
order by c.CustName

这不是查询编写的最佳方式......

但请使用以下内容替换查​​询中的折扣计算部分：

Discounts= (Select isnull(SUM(p.SalePrice * d.SoldQuantity* dr.DiscountRate/100),00.00) FROM OrderDetailsTbl d 
INNER JOIN  OrdersTbl o ON d.orderID = o.orderID INNER JOIN  ProductsTbl p ON p.ProductID = 
d.ProductID inner join DiscountRatesTbl dr on dr.orderID = o.orderID WHERE o.CustomerID = c.CustomerID ) ,

这样可行。

只需SUM必须包含所有乘数，而不是 p.SalePrice 和 d.SoldQuantity

的简单乘法
