Question

我有以下查询计算总数。我想计算运行总数而不是总计。我该如何修改查询？

请不要将其标记为重复，因为我必须修改此查询中的内容以获得所需的结果。查询构建是通过Windows应用程序用户选择动态完成的。

IF OBJECT_ID('tempdb..#mytemptable') IS NOT NULL
    DROP TABLE #mytemptable;

SELECT
    SUM(CAST([PT_100SCALED_VAL0] AS bigint)) AS PT_100SCALED_VAL0_TOTAL INTO #MYTEMPTABLE
FROM (
    SELECT
        t1.[timestamp],
        t1.[PT_100SCALED_VAL0]
    FROM [REPORT] t1
    WHERE CONVERT(DATE, t1.[timestamp]) = @timestamp
) TEMPTABLE

SELECT
    t1.[timestamp],
    t1.[PT_100SCALED_VAL0],
    RM_temp.*
FROM    [REPORT] t1,
        #MYTEMPTABLE RM_temp
WHERE
    CONVERT(DATE, t1.[timestamp]) = @timestamp

我目前的结果如下：

[timestamp]             [PT_100SCALED_VAL0] PT_100SCALED_VAL0_TOTAL
31/May/2016 12:01:37 PM 1                   87173
31/May/2016 12:02:07 PM 2                   87173
31/May/2016 12:02:37 PM 3                   87173
31/May/2016 12:03:07 PM 4                   87173

我希望它是：

[timestamp]             [PT_100SCALED_VAL0] PT_100SCALED_VAL0_TOTAL
31/May/2016 12:01:37 PM  1                  1
31/May/2016 12:02:07 PM  2                  3
31/May/2016 12:02:37 PM  3                  6
31/May/2016 12:03:07 PM  4                  10

试试这个

SELECT *,(SELECT SUM(pp.PT_100SCALED_VAL0) 
          FROM YourTable pp 
          WHERE pp.PT_100SCALED_VAL0 <= p.PT_100SCALED_VAL0
         ) AS RunningTotal
FROM YourTable p

我已使用以下

更新了您的INSERT INTO

SELECT
      (SELECT SUM(CAST(t2.[PT_100SCALED_VAL0] AS bigint)) 
       FROM  [REPORT] t2 
       WHERE t2.PT_100SCALED_VAL0 <= TEMPTABLE.[PT_100SCALED_VAL0] AND CONVERT(DATE, TEMPTABLE.[timestamp]) = @timestamp 
       )   AS PT_100SCALED_VAL0_TOTAL INTO #MYTEMPTABLE
FROM (
SELECT
    t1.[timestamp],
    t1.[PT_100SCALED_VAL0]
FROM [REPORT] t1
WHERE CONVERT(DATE, t1.[timestamp]) = @timestamp
) TEMPTABLE

插入临时表时计算运行总计
