Question

我有两个问题。第一个结果是仓库中零件的OnHand数量：

PartNum  OnHandQty  IUM
100009   19430.00   KG

第二个查询的结果是与仓库货物收据相关的交易：

TranDate     PartNum    TranQty     UM  Dayss
2014-09-01   100009     10720.000   KG  2
2014-09-01   100009     1340.000    KG  2
2014-08-11   100009     8710.000    KG  23
2014-08-11   100009     3350.000    KG  23
2014-06-30   100009     9380.000    KG  65

现在我需要计算 OnHandQy - TranQty ，直到它达到零，例如

19430 - 10720 = 8710 --not enough 
8710 - 1340 = 7370   --not enough 
7370 - 8710 = -1340  --enough

因此，我需要收到如下表格：

PartNum  OnHandQty  IUM  [0-10 Days]  [11-20 Days]   [over 21 Days]
100009   19430.00   KG   12060        null           8710

如何获得此结果的任何想法？

Answer 1

一个想法是使用以下查询。

WITH(TranDate,PartNum,TranQty,UM,Dayss) trans
AS
(
    -- Your second query
)
SELECT F.PartNum
    ,F.OnHandQty
    ,F.IUM  
    ,SUM(t0to10.TransQty) AS [0-10 Days]
    ,SUM(t11to20.TransQty) AS [11-20 Days]
    ,SUM(tover20.TransQty) AS [over 21 Days]
FROM (Your first query) AS F
    JOIN trans AS t0to10 ON F.PartNum = t0to10.PartNum 
        AND t0to10.Dayss BETWEEN 0 AND 10 
    JOIN trans AS t11to20 ON F.PartNum = t11to20.PartNum 
        AND t11to20.Dayss BETWEEN 11 AND 20
    JOIN trans AS tover20 ON F.PartNum = tover20.PartNum 
        AND tover20.Dayss >20 
GROUP BY F.PartNum,F.OnHandQty,F.IUM

Answer 2

声明OnHandQty并在while循环中使用游标将有助于对此进行排序。
