结合行通过代码

数据集：结合行通过代码

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) 
    values 
    ('ORANGES123', 10, 200, 500, '2017-04-01'), 
    ('BANANAS123', 15, 350, 900, '2017-04-01'), 
    ('APPLES123', 7, 234, 756, '2017-04-01'), 
    ('ORANGES123', 10, 200, 500, '2017-04-02'), 
    ('BANANAS123', 15, 350, 900, '2017-04-02'), 
    ('APPLES123', 7, 234, 756, '2017-04-02'); 



    CREATE TABLE Cancelled(

    CUnits int not null, 
    CCost int not null, 
    CPrice int not null, 
    CDate date not null

    Insert into Cancelled(Code, Cunits, Ccost, Cprice, Cdate) 
    values 
    ('ORANGES123', 3, 100, 200, '2017-04-01'),

Sqlfiddle这里：

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

背景：

我有2个表。返回表格和取消表格。我希望在过去一周内得到给定物料代码的总单位数/成本/价格总和。例如，从sqlfiddle，ORANGES123，我想我的查询返回：

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

这看似简单，但由于某种原因，当我在做的ItemCode我的两个表之间在SQL Server内部联接，单位之间“已取消”和“已退回”表格正在合并，计数在“已退回/已取消”之间受到交叉污染。

我觉得我错过了很简单的东西。

任何帮助，将不胜感激。

我正在使用的实际查询是在这里。我试图尽可能接近的sqlfiddle型号：

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

我们可以看到您的选择语句吗？ – jimmy8ball

你能否包含你的查询？ –

如果是我，我只有一张桌子，而不是两张桌子。 – Strawberry

开始用这个 - 我想你自己看着办休息了...

SELECT *, 'returned' source FROM returned 
UNION ALL 
SELECT *, 'cancelled' FROM cancelled; 
+------------+--------+-------+--------+------------+-----------+ 
| Code  | RUnits | RCost | RPrice | RDate  | source | 
+------------+--------+-------+--------+------------+-----------+ 
| ORANGES123 |  10 | 200 | 500 | 2017-04-01 | returned | 
| BANANAS123 |  15 | 350 | 900 | 2017-04-01 | returned | 
| APPLES123 |  7 | 234 | 756 | 2017-04-01 | returned | 
| ORANGES123 |  10 | 200 | 500 | 2017-04-02 | returned | 
| BANANAS123 |  15 | 350 | 900 | 2017-04-02 | returned | 
| APPLES123 |  7 | 234 | 756 | 2017-04-02 | returned |

谢谢，这让我足够了。 – jackfrost5234

您可以使用连接查询来实现这一点，遵循相同的结构来取消您的取消。

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
