如何在sql server中獲得此報告的查詢？

Question

我有這樣的SQL數據庫

而且我想告訴我的數據，如下列：

注：

總銷售額= SUM（ProductsTbl .SalePrice * OrderDetailsTbl.SoldQuantity）

個

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

祈禱，= SUM（ISNULL（CashMovementTbl.CashMovementValue，00.00）

所以，我該怎麼做在SQL Server中查詢以顯示類似的數據。

感謝您的任何幫助。

我嘗試這個查詢，但沒能得到折扣：

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

這不是書面查詢以最佳的方式...

，但有以下替換您的查詢的一部分折扣計算：

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) , 

這會起作用。

只需將SUM必須包括所有乘法器和p.SalePrice和d.SoldQuantity
