我正在尝试在 SQL 2008 中为正在运行的库存需求报告建立一个临时表。我可以得到我正在寻找的结果，直到我找到一张包含多行的发票。这是到目前为止的代码：

--Gather Current Order Data
DECLARE @b TABLE ([Planned Shipment Date] DATE, [Order] VARCHAR(15), [Line Number] VARCHAR(15), [Location] VARCHAR(15), [Item] VARCHAR(15), [QuantityUsed] INT)

INSERT INTO @b
SELECT [Planned Shipment Date], [Document No_], [Line No_], [Location Code], No_, CAST(SUM([Outstanding Quantity]) AS INT)
FROM [STAGE].[dbo].[TRU$Sales Line]
WHERE [Document No_] LIKE 'SO%'
AND [Gen_ Prod_ Posting Group] IN ('TOY', 'AUDIO', 'BICYCLE')
AND [Outstanding Quantity] <> 0
GROUP BY [Document No_], [Location Code], [Line No_], [Planned Shipment Date], No_
ORDER BY [Planned Shipment Date], [Document No_], [Line No_], [Location Code], No_

--Gather Current Inventory Data
DECLARE @a TABLE ([Item] VARCHAR(15), [Location] VARCHAR(15), [Inventory] INT)

INSERT INTO @a
SELECT [Item No_], [Location Code], CAST(SUM([Quantity]) AS INT)
FROM [STAGE].[dbo].[TRU$Item Ledger Entry]
GROUP BY [Item No_], [Location Code]
ORDER BY [Item No_], [Location Code]

DROP TABLE ##TEMP
--Insert to a temp table for testing
SELECT [Planned Shipment Date], [Location], [Item], [Order], [Line Number], 
[Outstanding Qty], [Total Inventory], [Running Order Total]
INTO ##TEMP
FROM
 (SELECT 
   [order].[Planned Shipment Date]
  ,[order].[Location] 
  ,[order].[Item] 
  ,[order].[Order]
  ,[order].[Line Number]
  ,0 AS [Outstanding Qty]
  ,(SELECT SUM(inventory)
    FROM @a inv
    WHERE inv.item = [order].[Item] 
    AND inv.location = [order].[Location]) AS [Total Inventory] 
  ,(SELECT SUM(QuantityUsed) 
    FROM @b prevorder 
    WHERE prevorder.item = [order].[Item] 
    AND prevorder.location = [order].[Location] 
    AND prevorder.[order] <= [order].[Order]
    ) AS [Running Order Total]
  FROM @b [order] 
 ) AS OrderExtended 
--WHERE [Total Inventory] < [Running Order Total]
ORDER BY [Planned Shipment Date], [Order], [Line Number], [Location], [Item] ASC
GO
--Display outstanding quantity to ship on the temp table
UPDATE ##TEMP
SET [Outstanding Qty] = SL.[Outstanding Quantity]
FROM ##TEMP T, [TRU$Sales Line] SL
WHERE T.[Order] = SL.[Document No_]
AND T.[Line Number] = SL.[Line No_]
GO

当我运行如下查询时：

SELECT * FROM ##TEMP
WHERE Item = '1011861'
ORDER BY [Order], [Line Number]

我得到类似的东西（未完成数量的不正确运行总数）：

Planned Shipment Date | Location | Item | Order | Line Number | Outstanding Qty | Total Inventory | Running Order Total
2010-08-20              HQ       1011861  SO18727    6          3                 49                 103

我所期待的是（一个真正的优秀数量的运行总数）：

Planned Shipment Date | Location | Item | Order | Line Number | Outstanding Qty | Total Inventory | Running Order Total
2010-08-20              HQ       1011861  SO18727    6          3                 49                 3

似乎当订单中包含不同的发货日期（每个订单多行）时，它会引发我的查询。我错过了什么？我看了这么多，恐怕我看不到明显的解决方案。

感谢您的帮助，道格

当 prevorder.Order=[order].Order 时，您必须限制 [Line Number]：

(SELECT SUM(QuantityUsed) FROM @b prevorder        
 WHERE prevorder.item = [order].[Item] AND prevorder.location = [order].Location]        
 AND (prevorder.[order] < [order].[Order] OR (prevorder.[order] = [order].[Order]         
 AND prevorder.[Line Number] <= [order].[Line Number]))         
 AS [Running Order Total]

按 [计划装运日期]、订单、[行号] 订购报告会更有用。

(SELECT SUM(QuantityUsed) FROM @b prevorder        
 WHERE prevorder.item = [order].[Item] AND prevorder.location = [order].Location]
 AND (prevorder.[Planned Shipment Date] < [order].[Planned Shipment Date] OR
 (prevorder.[Planned Shipment Date] = [order].[Planned Shipment Date]       
 AND (prevorder.[order] < [order].[Order] OR (prevorder.[order] = [order].[Order]         
 AND prevorder.[Line Number] <= [order].[Line Number])))         
 AS [Running Order Total]

变得太复杂？使用带有标识列 = RecordID 的表而不是 #temp 表。按记录应在报告中出现的顺序插入记录。 

(SELECT SUM(QuantityUsed) FROM @b prevorder        
 WHERE prevorder.Item = [order].[Item] AND prevorder.location = [order].Location]
 AND prevorder.RecordID <= [order].RecordID) AS [Running Order Total]
