难以获取以前的查询记录

Question

我在不同级别有 4 家商店。（A 店、B 店、C 店、D 店）。商店保留物品。（项目 1、项目 2、项目 3、项目 4 和项目 5）。

我有 3 tables（项目 Table，商店 Table， Tracking Table) 和 1 个查询 ( Store_rec query for Item2 in Store B).

跟踪 table 有列（ID、T_Date、Item_ID、Item_Name、Store_From、Store_To、金额、备注） .

Store_rec 查询 table 是检查商店中商品的更改（在我的例子中 - 商店 B 中的商品 2）。它有 5 列 (SrNo, T_Date, Location_To/From (From B to others/ From others to B), Received (B balance increase) and Dispatched (B balance decrease).

我的问题是：

我无法在不影响T_Date的行号的情况下对SrNo进行升序排序。
我想在 Store_rec 查询中添加余额列，如图所示。（余额 = 之前的余额 + 已接收 - 已发送）。

我在 Google 中搜索，阅读了论坛、教程和示例，但仍然无法解决我的问题。

请帮忙。

SELECT (
        SELECT COUNT(aa.[ID]) + 1
        FROM Tracking AS aa
        WHERE (
                t.[Store_From] = "Store B"
                OR t.[Store_To] = "Store B"
                )
            AND aa.[ID] < t.[ID]
        ) AS SrNo
    ,t.T_Date
    ,IIf(t.[Store_To] = "Store B", t.[Store_From], t.[Store_To]) AS [Location_To/From]
    ,IIf(t.[Store_To] = "Store B", t.[Amount], 0) AS Received
    ,IIf(t.[Store_From] = "Store B", t.[Amount], 0) AS Dispatched
FROM Tracking AS t
WHERE (
        t.[Store_From] = "Store B"
        OR t.[Store_To] = "Store B"
        )
    AND t.[Item_Name] = "Item 2"
ORDER BY t.[T_Date];

Answer 1

SELECT  id ,
        CASE WHEN Store_From = 'Store B' THEN Store_To
             ELSE Store_From
        END AS Location_To ,
        CASE WHEN Store_To = 'Store B' THEN 0
             ELSE Amount
        END AS Dispatched ,
        CASE WHEN Store_From = 'Store B' THEN 0
             ELSE Amount


        END AS Received
INTO    #Tmp
FROM    dbo.Tracking
WHERE   Item_Id = 'Item_2'
        AND ( Store_From = 'Store B'
              OR Store_To = 'Store B'
            )

SELECT  T1.Location_To ,       
        T1.Received ,T1.Dispatched ,
        SUM(T.Dispatched) AS RemainingBal
FROM    #Tmp AS T1
        LEFT JOIN ( SELECT  ISNULL(( -CAST(Dispatched AS INT) + CAST(Received AS INT) ),
                                   0) AS Dispatched ,
                            id
                    FROM    #Tmp
                  ) AS T ON T.id <= T1.id
GROUP BY T1.Location_To ,
        T1.Dispatched ,
        T1.Received

Answer 2

select  T1.id ,IIF(Store_From = 'Store B',Store_To, Store_From) ,IIF(Store_To = 'Store B',0, Amount) AS Dispatched, IIF(Store_From = 'Store B',0, Amount) AS Received,SUM(T.Received) AS RemainingBal
  From track  as T1

left join (

select  id,(-IIF(Store_To = 'Store B',0, Amount) + IIF(Store_From = 'Store B',0, Amount) ) AS Received
  From track 

) as  T ON T.id <= T1.id

WHERE   Item_Id = 'Item_2'
        AND ( Store_From = 'Store B'
              OR Store_To = 'Store B'
            )

GROUP BY 
        T1.Store_From ,
        T1.Store_To,T1.id,Amount
        ORDER BY T1.id

Answer 3

感谢您对我的帮助。我在上面提供的代码中编辑了一些点。代码如下

SELECT T1.TDate,IIF(T1.Store_From = 'Store B',T1.Store_To, T1.Store_From) AS Location, IIF(T1.Store_From = 'Store B',0, T1.Amount) AS Received, IIF(T1.Store_To = 'Store B',0, T1.Amount) AS Dispatched, SUM(T.Received) AS Balance FROM Tracking AS T1 LEFT JOIN (SELECT aa.id, aa.TDate, (-IIF(aa.Store_To = 'Store B',0, aa.Amount) + IIF(aa.Store_From = 'Store B',0, aa.Amount) ) AS Received FROM Tracking AS aa WHERE aa.Item_Name = 'Item 2')  AS T ON T.id <= T1.id WHERE Item_Name = 'Item 2' AND (Store_From = 'Store B' OR Store_To = 'Store B') GROUP BY T1.TDate,T1.Store_From, T1.Store_To, T1.id, Amount ORDER BY T1.TDate;
