根据日期范围计算数量总和

Question

在下面的查询中，我有3个表GoodsReceivedNote ， GoodsReceivedNoteDetail和TransferNote 。 在GoodsReceivedNote和GoodsReceivedNoteDetail我将在特定日期的特定日期接收产品。 在TransferNote我将产品从一个位置转移到另一位置。 我的目标是要总结基于产品的转移数量grn接收日期的日期startdate和在该产品的下一个接收日期grn作为end date 。 在这里，我将显示示例。

[GoodsReceivedNote]    
GoodsReceivedNoteID | LocationID
--------------------+---------------
     1              |      1
     2              |      1

[GoodsReceivedNoteDetail]
GoodsReceivedNoteDetailID|GoodsReceivedNoteID|AcceptedQuantity|ProductID|CreatedON
-------------------------+-------------------+----------------+---------+-----------
    1                    | 1                 | 50             |  1      | 10-2-2015
    2                    | 2                 | 100            |  1      | 1-3-2015

[TransferNote]
Fromlocation |Tolocation|ProductID|TransferQuantity|CreatedOn  |
-------------+----------+---------+----------------+-----------+
 1              2             1       10           | 10-2-2015
 1              2             1       25           | 12-2-2015
 1              2             1       50           | 5-3-2015

我的预期结果：

GoodsReceivedNoteID|LocationID|AcceptedQuantity|ProductID|CreatedOn|Fromlocation |Tolocation|ProductID|TransferQuantity
-------------------+----------+----------------+---------+---------+-------------+----------+---------+-----------------
1                  | 1        | 50             |   1     |10-2-2015|   1         |   2      |   1     |  35      
2                  | 2        | 100            | 1       |  1-3-15 |   1         |   2      |   1     |  50  


Select 
dbo.fn_MaterialTransferqty(GRN.LocationID,GRND.ProductID,GRND.CreatedON,GRND.CreatedON )
From GoodsReceivedNoteDetail GRND 
LEFT OUTER JOIN GoodsReceivedNote GRN ON GRN.GoodsReceivedNoteID =GRND.GoodsReceivedNoteID
LEFT OUTER JOIN TransferNote TN ON Tn.ProductID=GRND.ProductID

Select GRN.LocationID,GRND.ProductID,GRND.ReceivedQuantity,
dbo.fn_MaterialTransferqty(GRN.LocationID,GRND.ProductID,GRND.CreatedOn,GRND.CreatedOn)
From GoodsReceivedNoteDetail GRND 
LEFT OUTER JOIN GoodsReceivedNote GRN ON GRN.GoodsReceivedNoteID =GRND.GoodsReceivedNoteID
LEFT OUTER JOIN TransferNote TN ON Tn.ProductID=GRND.ProductID
WHERE GRND.CreatedOn >=@i_StartDate AND   GRND.CreatedOn<=@i_EndDate

Answer 1

这只是一个猜测。 部分原因对我来说没有意义。

select
    grn.GoodsReceivedNoteID, grn.LocationID,
    grnd.AcceptedQuantity, grnd.ProductID, grnd.CreatedOn,
    tn.Fromlocation, tn.Tolocation, tn.ProductID, /* why do you want this twice? */
    sum(TransferQuantity) as TransferQuantity
from
    GoodsReceivedNote as grn
    inner join GoodsReceivedNoteDetail as grnd
        on  grnd.GoodsReceivedNoteID = grn.GoodsReceivedNoteID
    inner join TransferNote as tn
        on  tn.Fromlocation = grn.LocationID
            and tn.ProductID = grn.ProductID /* is this correct? */
group by
    grn.GoodsReceivedNoteID, grn.LocationID,
    grnd.AcceptedQuantity, grnd.ProductID, grnd.CreatedOn,
    tn.Fromlocation, tn.Tolocation, tn.ProductID

Answer 2

这将返回每个产品grn的开始和结束日期，并对这两个日期之间的转移产生的数量求和：

select distinct grn.ProductID, grn.CreatedON StartDate, 
    (select min(CreatedON) from GoodsReceivedNoteDetail 
        where ProductID = grn.ProductID and CreatedON > grn.CreatedON
    ) EndDate,
    (select sum(TransferQuantity) from TransferNote
        where ProductID = grn.ProductID
        and CreatedOn >= grn.CreatedON 
        and CreatedOn <= 
            (select min(CreatedON) from GoodsReceivedNoteDetail 
                where ProductID = grn.ProductID and CreatedON > grn.CreatedON)
    ) Quantity
from GoodsReceivedNoteDetail grn

EndDate计算为产品以grn为单位的下一个日期。 数量是grn中StartDate和EndDate之间（包括）在TransferNote中的TransferQuantity的总和。
