Question

运行SQL 2008 R2。此proc在VS 2008 DB Project中通过了验证，但在管理工作室中失败了。有什么想法吗？

对于赋值，部分，您可以在子查询的帮助下进行处理，例如：

Select @ItemID = ItemID, @LotTrackIND = LotTrackingInd, @LotNumber = LotNumber
  from (
        SELECT i.ItemID, i.LotTrackingInd, '' LotNumber
        FROM WRHS_ItemUOM iu
        INNER JOIN WRHS_Item i ON iu.ItemID = i.ItemID
        WHERE iu.BarcodeNumber = @BarCodeNumber
        UNION
        SELECT i.ItemID, i.LotTrackingInd, wil.LotNumber
        FROM WRHS_WarehouseItemLotIdentify wili
        INNER JOIN WRHS_WarehouseItemLot wil ON wili.WarehouseItemLotID = wil.WarehouseItemLotID
        INNER JOIN WRHS_WarehouseItem wi ON wil.WarehouseItemID = wi.WarehouseItemID
        INNER JOIN WRHS_Item i ON wi.ItemID = i.ItemID
        WHERE wili.ItemIdentification = @BarCodeNumber
       ) q1

我想你没有迭代你的查询可能返回的（可能的）多条记录。

最好的问候。

你工会中的

你不能做变量作业

SELECT @ItemID = i.ItemID, @LotTrackIND = i.LotTrackingInd, @LotNumber = ''  
...
UNION
SELECT @ItemID = i.ItemID, @LotTrackIND = i.LotTrackingInd, @LotNumber = wil.LotNumber 
...

正如错误所说。

至于为什么它在VS中传递，这是一个VS错误。

Answer 3

是的，错误就在这部分，

SELECT @ItemID = i.ItemID, @LotTrackIND = i.LotTrackingInd, @LotNumber = '' 
FROM WRHS_ItemUOM iu 
INNER JOIN WRHS_Item i ON iu.ItemID = i.ItemID 
WHERE iu.BarcodeNumber = @BarCodeNumber 
UNION 
SELECT @ItemID = i.ItemID, @LotTrackIND = i.LotTrackingInd, @LotNumber = wil.LotNumber 
FROM WRHS_WarehouseItemLotIdentify wili 
INNER JOIN WRHS_WarehouseItemLot wil ON wili.WarehouseItemLotID = wil.WarehouseItemLotID 
INNER JOIN WRHS_WarehouseItem wi ON wil.WarehouseItemID = wi.WarehouseItemID 
INNER JOIN WRHS_Item i ON wi.ItemID = i.ItemID 
WHERE wili.ItemIdentification = @BarCodeNumber

如果语句具有UNION，则无法使用select语句为变量赋值。如果你考虑一下，它没有意义。变量只能包含一个值，但应该选择哪个值？第一个选择语句或第二个语句中的一个？

你必须明确做出这个选择。假设您希望第二个select语句优先（即从第二个select中取值。如果第二个select语句没有返回值，那么取第一个返回的值），你可以这样做

SELECT @ItemID = i.ItemID, @LotTrackIND = i.LotTrackingInd, @LotNumber = '' 
FROM WRHS_ItemUOM iu 
INNER JOIN WRHS_Item i ON iu.ItemID = i.ItemID 
WHERE iu.BarcodeNumber = @BarCodeNumber 

SELECT @ItemID = i.ItemID, @LotTrackIND = i.LotTrackingInd, @LotNumber = wil.LotNumber 
FROM WRHS_WarehouseItemLotIdentify wili 
INNER JOIN WRHS_WarehouseItemLot wil ON wili.WarehouseItemLotID = wil.WarehouseItemLotID 
INNER JOIN WRHS_WarehouseItem wi ON wil.WarehouseItemID = wi.WarehouseItemID 
INNER JOIN WRHS_Item i ON wi.ItemID = i.ItemID 
WHERE wili.ItemIdentification = @BarCodeNumber

在包含顶级UNION，INTERSECT或EXCEPT运算符的语句中不允许进行变量赋值
