Question

我有4张桌子，如下所示。下面给出的四个表的概要。

InventoryTransferHeader

TrasferCode   | TransferDate | FromOutlet|   T0Outlet  
------------- |------------- |---------- |-----------  
SYS000022     |  2016-03-08  |   710     |     707

InventoryTransferLine

TransferCode |ItemCode   |ItemDescription| Qty  
-------------|---------- |---------------|----  
 SYS000022   | 7000000064| ABCD          |   4    
 SYS000022   | 5000000087| PQRS          |   4

InventoryTransferSerials

TransferCode |ItemCode   |SerialNo  
-------------|---------- |-------------  
SYS000022    | 7000000064| 777777777798829  
SYS000022    | 7000000064| 777777777798830  
SYS000022    | 7000000064| 777777777798831  
SYS000022    | 7000000064| 777777777798832  
SYS000022    | 5000000087| 124536850888  
SYS000022    | 5000000087| 124536850889  
SYS000022    | 5000000087| 124536850890  
SYS000022    | 5000000087| 124536850891

插座

OutletCode | OutletDesc  
-----------|-------------  
707        | ABC  
710        | XYZ

我想要输出如下。

TransferCode | TransferDate | FromOutlet | ToOutlet | ItemCode | ItemDescription |SerialNo | Qty  
-------------|--------------|------------|----------|----------|----------------|-------------|--------    
 SYS000022   | 2016-03-08   | XYZ        | ABC      |5000000087|PQRS             |124536850888,124536850889,124536850890,124536850891|4    
SYS000022    | 2016-03-08   | XYZ        | ABC      |7000000064|ABCD             |777777777798829 ,777777777798830 ,777777777798831 ,777777777798832 |4

而不是获得两行，我得到八行。这是我使用的代码。

SELECT
    ISNULL(InventoryTransferHeader.TransferCode,'') AS 'TransferId',
    ISNULL(InventoryTransferHeader.TransferDate,'') AS 'TransferDate',
    ISNULL(InventoryTransferLine.ItemCode,'') AS 'ItemCode',
    ISNULL(InventoryTransferLine.ItemDescription,'') AS 'ItemDescription',
    ISNULL(InventoryTransferLine.Qty,'') AS 'Quantity',

    STUFF((SELECT '/' + InventoryTransferSerials.SerialNo 
           FROM InventoryTransferSerials
           WHERE InventoryTransferSerials.ItemCode =    InventoryTransferLine.ItemCode AND 
           InventoryTransferSerials.TransferCode = InventoryTransferLine.TransferCode

           FOR XML PATH('')),1,1,'') AS 'SN',


    ISNULL(InventoryTransferHeader.FromOutlet,'') AS 'outletFrom' ,
    ISNULL(F.OutletDesc,'') AS 'Outlets',
    ISNULL(InventoryTransferHeader.TOOutlet,'') AS 'outletTO' ,
    ISNULL(T.OutletDesc,'') AS 'Outlets' 

FROM    InventoryTransferHeader
    INNER JOIN
    Outlets F ON InventoryTransferHeader.FromOutlet = F.OutletCode
    INNER JOIN
    Outlets T ON InventoryTransferHeader.ToOutlet = T.OutletCode 
    LEFT OUTER JOIN
    InventoryTransferLine ON InventoryTransferLine.TransferCode = InventoryTransferHeader.TransferCode 
    LEFT OUTER JOIN
    InventoryTransferSerials ON InventoryTransferSerials.TransferCode = InventoryTransferLine.TransferCode 
    AND InventoryTransferSerials.ItemCode = InventoryTransferLine.ItemCode


WHERE (InventoryTransferHeader.TransferCode = 'SYS000022')

Answer 1

删除

LEFT OUTER JOIN
    InventoryTransferSerials ON InventoryTransferSerials.TransferCode = InventoryTransferLine.TransferCode 
    AND InventoryTransferSerials.ItemCode = InventoryTransferLine.ItemCode

您已经在查询中获得序列号为SN

您加入InventoryTransferSerials，因此表中有4个序列号InventoryTransferSerials foreach InventoryTransferLine行

SQL Server中的行重复
