結合行通過代碼

數據集：結合行通過代碼

CREATE TABLE Returned(
    Code varchar(20) not null, 
    RUnits int not null, 
    RCost int not null, 
    RPrice int not null, 
    RDate date not null); 


    Insert into Returned(Code, Runits, rcost, rprice, rdate)

Sqlfiddle這裏：

http://sqlfiddle.com/#!9/f10634

背景：

我有2個表。返回表格和取消表格。我希望在過去一週內得到給定物料代碼的總單位數/成本/價格總和。例如，從sqlfiddle，ORANGES123，我想我的查詢返回：

ItemCode , TotalReturnedUnits, TotalReturnedCost, TotalReturnedPrice,TotalCancelledUnits, TotalCancelledCost, TotalCancelledPrice 
ORANGES123,     20,    400,    1000,     6,    200,     400

這看似簡單，但由於某種原因，當我在做的ItemCode我的兩個表之間在SQL Server內部聯接，單位之間「已取消」和「已退回」表格正在合併，計數在「已退回/已取消」之間受到交叉污染。

我覺得我錯過了很簡單的東西。

任何幫助，將不勝感激。

我正在使用的實際查詢是在這裏。我試圖儘可能接近的sqlfiddle型號：

SELECT sales.Code AS Code, 
     sales.Quantity AS QtyReturned, 
     price.WghtAvgCost * sales.Quantity AS ReturnedCost, 
     price.CurrentPrice * sales.Quantity AS ReturnedPrice, 
     orders.CancelledUnits, 
     orders.CancelledCost, 
     orders.CancelledPrice, 
     price.CurrentPriceType AS PriceType 
FROM salesTable sales 
    INNER JOIN costPriceTable price ON sales.Code= price.Code 
                AND (sales.BusinessDate BETWEEN price.StartDate AND price.EndDate) 
                AND sales.LocationId = price.LocationId 
    INNER JOIN ordersTable orders 
     ON sales.Code= orders.Code

我們可以看到您的選擇語句嗎？ – jimmy8ball

你能否包含你的查詢？ –

如果是我，我只有一張桌子，而不是兩張桌子。 – Strawberry

開始用這個 - 我想你自己看着辦休息了...

謝謝，這讓我足夠了。 – jackfrost5234

您可以使用連接查詢來實現這一點，遵循相同的結構來取消您的取消。

JOIN 
(SELECT 
Code, sum(RUnits) as TotalReturnedUnits, sum(RCost) as TotalReturnedCost, 
sum(RPrice) as TotalReturnedPrice 
from Returned 
where 

--parameterised dates can be used 
--RDate between @Start and @End 

group by Code 
)returns 
ON salesTable.Code = returns.Code
