我正在使用Microsoft SQL Server 2012。
我有一个包含项目交易的表格：
artcode transdate Qty transactionvalue
------------------------------------------------
M100 2010-11-24 6.00 179.40
M100 2010-11-24 -6.00 -179.4
M100 2010-11-25 100.00 2900.00
M100 2010-11-26 -1.00 -29
M100 2010-11-26 -5.00 -145
M100 2010-11-26 -1.00 -29
M100 2010-11-29 -5.00 -145
M100 2010-11-29 -3.00 -87
M100 2010-11-29 -1.00 -29
通过此查询，我设法以运行顺序获取累积值：
SELECT
TransDate, ArtCode, CumulativeQuantity, CumulativeValue
FROM
(SELECT
ArtCode,
SUM(CAST(REPLACE(REPLACE(NULLIF(Qty, ''), ',', '.'), ' ', '') AS float)) OVER (PARTITION BY artcode ORDER BY transdate) AS CumulativeQuantity,
SUM(CAST(REPLACE(REPLACE(NULLIF(TotCostPrice, ''), ',', '.'), ' ', '') AS FLOAT)) OVER (PARTITION BY artcode ORDER BY transdate) AS CumulativeValue,
TransDate
FROM
stage_itemhistory
WHERE
artcode = 'm100' AND stockaffect = 1) S
GROUP BY
TransDate, ArtCode, CumulativeQuantity, CumulativeValue
返回：
TransDate ArtCode CumulativeQuantity CumulativeValue
--------------------------------------------------------
2010-11-24 M100 0 0
2010-11-25 M100 100 2900
2010-11-26 M100 93 2697
2010-11-29 M100 84 2436
这与我所追求的非常接近，唯一缺少的是日期之间的日期，即之前的日期累计值。所以它看起来像这样：
TransDate ArtCode CumulativeQuantity CumulativeValue
--------------------------------------------------------
2010-11-24 M100 0 0
2010-11-25 M100 100 2900
2010-11-26 M100 93 2697
2010-11-27 M100 93 2697
2010-11-28 M100 93 2697
2010-11-29 M100 84 2436
任何和所有帮助将不胜感激！提前谢谢。

这比我想象的要难。有人可能会有一个更简单的解决方案。需要填写艺术代码并考虑不同艺术代码的不同范围。
declare @T table (artcode varchar(10), transdate date, Qty smallmoney, transactionvalue smallmoney);
insert into @T values
('M100', '2010-11-24', 6.00, 179.40)
, ('M100', '2010-11-24', -6.00, -179.4)
, ('M100', '2010-11-25', 100.00, 2900.00)

解决这个问题的方法是使用CTE一年中的所有日子（或所需的时间跨度），然后适当地使用left join，如下所示：
with Calendar as (
select CAST('2010-01-01' as date) [transdate], 0 [Qty], 0 [transactionvalue]
union all
select DATEADD(DAY, 1, [transdate]), 0, 0 from Calendar
where [transdate] < '2010-12-31'
), with Calendar2 ([artcode], [transdate], [Qty], [transactionvalue]) as (
select [T].artcode, [C].* from Calendar [C]
cross join (select distinct artcode from MY_TABLE) [T]
)
select [a].[artcode], [a].[transdate], isnull([b].[Qty],[a].[Qty]),isnull([b].[transactionvalue],[a].[transactionvalue]) from Calendar2 [a]
left join MY_TABLE [b] on ([a].transdate = [b].transdate and [a].[artcode] = [b].[artocde])
option(maxrecursion 0)

如果您没有日历或计数表，则可以使用临时计数表
另外，假设用ArdCode划分
示例
;with cte as (
SELECT
TransDate, ArtCode, CumulativeQuantity, CumulativeValue
FROM
(SELECT
ArtCode,
SUM(CAST(REPLACE(REPLACE(NULLIF(Qty, ''), ',', '.'), ' ', '') AS float)) OVER (PARTITION BY artcode ORDER BY transdate) AS CumulativeQuantity,
SUM(CAST(REPLACE(REPLACE(NULLIF(TotCostPrice, ''), ',', '.'), ' ', '') AS FLOAT)) OVER (PARTITION BY artcode ORDER BY transdate) AS CumulativeValue,
TransDate
FROM
stage_itemhistory
WHERE
artcode = 'm100' AND stockaffect = 1) S
GROUP BY
TransDate, ArtCode, CumulativeQuantity, CumulativeValue
)
Select TransDate = B.D
,A.ArtCode
,A.CumulativeQuantity
,A.CumulativeValue
From (
Select *
,NextDate = lead([TransDate],1,dateadd(day,1,[TransDate])) over (partition by ArtCode order by [TransDate])
From cte
) A
Cross Apply (
Select Top (DateDiff(DAY,[TransDate],NextDate)) D=DateAdd(DAY,-1+Row_Number() Over (Order By (Select Null)),[TransDate]) From master..spt_values n1,master..spt_values n2
) B
返回
TransDate ArtCode CumulativeQuantity CumulativeValue
2010-11-24 M100 0 0
2010-11-25 M100 100 2900
2010-11-26 M100 93 2697
2010-11-27 M100 93 2697
2010-11-28 M100 93 2697
2010-11-29 M100 84 2436

我找到了一个适合我的解决方案：
--Create TempTable
CREATE TABLE #TempTable(
TransDate Date,
ArtCode varchar(150),
CumulativeQuantity float(53),
CumulativeValue float(53))
--Insert Cumulative data, still missing dates
insert into #TempTable (TransDate, ArtCode, CumulativeQuantity, CumulativeValue)
SELECT TransDate, ArtCode, CumulativeQuantity, CumulativeValue FROM (
select ArtCode,
SUM(Qty) OVER (partition by artcode order by transdate) AS CumulativeQuantity,
SUM(TotCostPrice) OVER (partition by artcode order by transdate) AS CumulativeValue,
TransDate
from stage_itemhistory where stockaffect=1
) S
group by TransDate, ArtCode, CumulativeQuantity, CumulativeValue;
--Select all with Missing dates with previous dates data
WITH CTE as (
SELECT TransDate, ArtCode, CumulativeQuantity, CumulativeValue FROM #TempTable
UNION ALL
select DATEADD(Day,1,TransDate), ArtCode, CumulativeQuantity, CumulativeValue FROM CTE e
Where Not Exists (select * from #TempTable e2 where e2.TransDate = DATEADD(DAY,1,e.TransDate) and e.ArtCode=e2.ArtCode)
and TransDate < GETDATE()
)
select TransDate,
ArtCode,
CumulativeQuantity,
ROUND(CumulativeValue,2)
from CTE where TransDate > '2016-01-01'
Order by ArtCode, TransDate
