Sql server 2008 是否向TSQL查询（SQL Server 2008）添加累积（运行）总计？

我有以下查询，显示特定日期范围内的每周总计：

declare @from_date datetime
declare @to_date datetime

SET @from_date = '2014-03-30';    
SET @to_date = '2014-08-10';    

SELECT DATEDIFF(week, 0, IDOC.Import_Date) Week,
    DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) 'From Date',
    DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) + 6 'End Date',
    COUNT(IDOC.IDOC_ID) 'Total'
FROM IDOC    
INNER JOIN dbo.File_Type FI     
        on IDOC.File_Type_ID = FI.File_Type_ID    
INNER JOIN  IDOC_Team_Assignment ITA    
    ON IDOC.IDOC_ID=ITA.IDOC_ID    
Where IDOC.Import_Date BETWEEN @from_date AND @to_date
GROUP BY DATEDIFF(week, 0, IDOC.Import_Date) 
ORDER BY DATEDIFF(week, 0, IDOC.Import_Date)

输出：

Week    | From Date      | End Date      | Total
--------------------------------------------------
5965    2014-04-28    2014-05-04        1
5967    2014-05-12    2014-05-18      1
5968    2014-05-19    2014-05-25      2

xQbert提供给您的链接向您展示了这个概念，但是当您的select中已经有另一个计数时，它可能会有点混乱

您需要删除您的分组，并在两个计数上使用over，将一个限制为仅在您已经拥有的分组上计数，第二个覆盖整个范围

在这种情况下，不能使用前面未绑定的行，因为它将为每一行创建一个条目，而不是在现有结果集上构建。但您确实需要在结束时和选择结束时保持订单同步

您还需要添加不同的关键字

SELECT DISTINCT
    DATEDIFF(week, 0, IDOC.Import_Date) Week,
    DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) 'From Date',
    DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) + 6 'End Date',
    COUNT(IDOC.IDOC_ID) OVER (PARTITION BY DATEDIFF(week, 0, IDOC.Import_Date)) 'Total',
    COUNT(IDOC.IDOC_ID) OVER (ORDER BY DATEDIFF(week, 0, IDOC.Import_Date)) 'Running Total'
FROM IDOC    
INNER JOIN dbo.File_Type FI     
        on IDOC.File_Type_ID = FI.File_Type_ID    
INNER JOIN  IDOC_Team_Assignment ITA    
    ON IDOC.IDOC_ID=ITA.IDOC_ID    
WHERE IDOC.Import_Date BETWEEN @from_date AND @to_date
ORDER BY DATEDIFF(week, 0, IDOC.Import_Date)

我不能在SQL Server 2008上测试它，但我确实在VS2013免费提供的任何软件中测试了它，我知道它在Oracle中也能工作。值得一试

这一个是在SQL Server 2008 R2上测试的-我希望您不要急于获取此数据

SELECT
    DATEDIFF(week, 0, IDOC.Import_Date) Week,
    DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) 'From Date',
    DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) + 6 'End Date',
    COUNT(IDOC.IDOC_ID) 'Total',
    (
        SELECT
            COUNT(aIDOC.IDOC_ID)
        FROM
            IDOC aIDOC
        INNER JOIN dbo.File_Type aFI     
            ON aIDOC.File_Type_ID = aFI.File_Type_ID    
        INNER JOIN IDOC_Team_Assignment aITA    
            ON aIDOC.IDOC_ID=aITA.IDOC_ID    
        WHERE
            aIDOC.Import_Date BETWEEN @from_date AND @to_date
            AND DATEDIFF(week, 0, IDOC.Import_Date) <= DATEDIFF(week, 0, aIDOC.Import_Date)
    ) 'RunningTotal'
FROM
    IDOC
INNER JOIN dbo.File_Type FI     
    ON IDOC.File_Type_ID = FI.File_Type_ID    
INNER JOIN  IDOC_Team_Assignment ITA    
    ON IDOC.IDOC_ID=ITA.IDOC_ID    
WHERE
    IDOC.Import_Date BETWEEN @from_date AND @to_date
GROUP BY
    DATEDIFF(week, 0, IDOC.Import_Date) 
ORDER BY
    DATEDIFF(week, 0, IDOC.Import_Date)

现在我把它改成了CTE，在我看来更干净

WITH CTE( WeekNbr, FromDate, EndDate, Total) AS (
    SELECT
        DATEDIFF(week, 0, IDOC.Import_Date) 'WeekNbr',
        DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) 'FromDate',
        DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) + 6 'EndDate',
        COUNT(IDOC.IDOC_ID) 'Total'
    FROM
        IDOC
    INNER JOIN dbo.File_Type FI     
        ON IDOC.File_Type_ID = FI.File_Type_ID    
    INNER JOIN  IDOC_Team_Assignment ITA    
        ON IDOC.IDOC_ID=ITA.IDOC_ID    
    WHERE
        IDOC.Import_Date BETWEEN @from_date AND @to_date
    GROUP BY
        DATEDIFF(week, 0, IDOC.Import_Date) 
)
SELECT
    A.WeekNbr,
    A.FromDate,
    A.EndDate,
    A.Total,
    (SELECT SUM(B.Total) FROM CTE B WHERE B.WeekNbr <= A.WeekNbr) 'RunningTotal'
FROM
    CTE A
ORDER BY
    A.WeekNbr

你想要的是一个连续的总数，而不是一个累积的总数。该链接向您展示了如何做到这一点；在SQL Server 2008中，如果没有临时表，这看起来不是很简单吗？谢谢你给我这个很好的例子。我需要弄清楚为什么它的编码是：COUNTIDOC.IDOC\u ID OVER ORDER BY DATEDIFFweek，0，IDOC.Import\u Date“Running Total”在“ORDER”附近的语法不正确。这可能是因为SQL Server 2008无法做到这一点，但微软说是这样。我查看了文档：2008年不可能使用ORDER BY with OVER，我的意思是

WITH CTE( WeekNbr, FromDate, EndDate, Total) AS (
    SELECT
        DATEDIFF(week, 0, IDOC.Import_Date) 'WeekNbr',
        DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) 'FromDate',
        DATEADD(week, DATEDIFF(week, 0, IDOC.Import_Date), 0) + 6 'EndDate',
        COUNT(IDOC.IDOC_ID) 'Total'
    FROM
        IDOC
    INNER JOIN dbo.File_Type FI     
        ON IDOC.File_Type_ID = FI.File_Type_ID    
    INNER JOIN  IDOC_Team_Assignment ITA    
        ON IDOC.IDOC_ID=ITA.IDOC_ID    
    WHERE
        IDOC.Import_Date BETWEEN @from_date AND @to_date
    GROUP BY
        DATEDIFF(week, 0, IDOC.Import_Date) 
)
SELECT
    A.WeekNbr,
    A.FromDate,
    A.EndDate,
    A.Total,
    (SELECT SUM(B.Total) FROM CTE B WHERE B.WeekNbr <= A.WeekNbr) 'RunningTotal'
FROM
    CTE A
ORDER BY
    A.WeekNbr
