从一列中减去另一列并获得运行 SQL Server 2008 R2 的总容量

Question

我讨厌问一个问题，似乎答案已经存在于某处，但过去几天我一直在研究各种文章（https://www.sqlshack.com/running-running-totals-sql -server/、计算 SQL Server 中的运行总计、https://learn.microsoft.com/en-us/sql/t-sql/queries/with-common-table-expression-transact-sql? view=sql-server-2017 等），进展甚微。

似乎给出的大多数示例都提供了一种连接方式（自连接）或其他一些

WHERE

子句来缩小结果集？无论如何，我有一个表

Location

，其中包含

PassengersOn

和

PassengersOff

列；我希望能够计算给定时间船上乘客的运行总数，以便我的结果表可能看起来像这样

显示每个地点后乘客的运行总数 (

OnBoard

)。

此外，我知道 SQL Server 2012 中提供了 OVER 子句，但不幸的是我使用的是 2008 R2。

再次抱歉可能是重复的问题，但我不知道如何根据联接或

WHERE

子句限制我的结果集，因为我的“位置”表中没有递增列，而是它使用指南。

编辑：这是表格信息的示例

Answer 1

我觉得如果你要为表建立索引，你可以非常简单地做到这一点。我通过位置创建了一个编号索引。如果您有这 10 个站点的相同路线，并且数据一遍又一遍地重复 loc1-loc10，您就不会想使用它。您需要一个主键或一个日期系统来使这变得更加容易。

SELECT  CONVERT(INT, RIGHT(Location, LEN(Location) - 3)) AS ID
    ,Location
    ,Passengerson
    ,PAssengersoff
INTO #IDtable
FROM #table

SELECT  ID 
    ,Location
    ,Passengerson
    ,Passengersoff
    ,(SELECT SUM(passengerson-passengersoff)
      FROM #IDtable b
      WHERE b.ID <= a.ID) AS Total
FROM #IDtable a
ORDER BY ID

这将给出如下所示的结果：

希望这对您有所帮助。

Answer 2

我无法访问 2008 R2，但此解决方案应该可以从 2005+ 开始工作。 这是提供的第二个链接的中间页面。

;with MyData as(
select 'loc1' [location], 69 PassengersOn, 0 PassengersOff
union all select 'loc2',61,0
union all select 'loc3',333,0
union all select 'loc4',57,21
union all select 'loc5',49,29
)


SELECT 
MyData.*
,RunningTotal.*

FROM MyData
cross apply (select 
                --SUM(PassengersOn)  PassOn
                --,SUM(PassengersOff) PassOff
                SUM(PassengersOn) - SUM(PassengersOff) as RunningTot

                from MyData MyDataApply
                where MyDataApply.[location]<= MyData.[location]
            ) as RunningTotal

ORDER BY MyData.[location]
