T-SQL-2个日期之间的两个日期时间之间的每小时秒数

标签： sql-server tsql date datetime

我有以下数据用于用户登录和注销时间：

我需要弄清楚每个唯一日期的每小时，用户登录的时间（IE StartDate到EndDate）。

我发现了这个post对此进行了讨论，到目前为止，这是我的查询，但它没有考虑到跨越2个日期（6/24至6/25）的第1行的小时数

WITH Numbers (Number) AS
(   SELECT ROW_NUMBER() OVER(ORDER BY N1.N) - 1
    FROM (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) N1(N)

    CROSS JOIN (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) N3 (N)
    CROSS JOIN (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) N4 (N)
), SampleData (userid, StartDate, EndDate) AS
(   SELECT  userid, CONVERT(DATETIME2, StartDate), CONVERT(DATETIME2, EndDate)
    FROM (VALUES 
            (1033, '06/24/2018 23:00:52', '06/25/2018 01:24:53'),
            (1033, '06/25/2018 02:01:58', '06/25/2018 02:03:47'),
            (1033, '06/25/2018 03:01:57', '06/25/2018 03:45:59')
        ) d (userid, StartDate, EndDate)
)
SELECT  d.userid,
        [Date] = CONVERT(DATE, d.StartDate),
        [Hour] = CONVERT(TIME(0), DATEADD(HOUR, DATEPART(HOUR, d.StartDate) + n.Number, 0)),
        Seconds_in = CASE  
                        -- SPECIAL CASE: START HOUR = END HOUR
                        WHEN DATEPART(HOUR, d.StartDate) = DATEPART(HOUR, d.EndDate)
                            AND DATEDIFF(DAY, d.StartDate, d.EndDate) = 0
                            THEN DATEDIFF(second, d.StartDate, d.EndDate)

                        WHEN CONVERT(DATE, d.StartDate)<CONVERT(DATE, d.EndDate) then ?????

                        -- START HOUR
                        WHEN n.Number = 0
                            THEN 3600 - DATEPART(second, d.StartDate)

                        -- END HOUR
                        WHEN n.Number = DATEDIFF(HOUR, d.StartDate, d.EndDate) 
                            THEN DATEPART(second, d.EndDate)

                        -- FULL HOURS IN BETWEEN START AND END
                        ELSE 3600

                    END
FROM    SampleData d
        INNER JOIN Numbers n 
            ON n.Number <= DATEDIFF(HOUR, d.StartDate, d.EndDate)
ORDER BY d.userid,[Date],n.Number;

理想的结果如下：

 | UserID | Date      | Hour     |  Seconds_in |
 | 1033   | 6/24/2018 | 23:00:00 |  3548       |
 | 1033   | 6/25/2018 | 0:00:00  |  3600       |
 | 1033   | 6/25/2018 | 1:00:00  |  1493       |
 | 1033   | 6/25/2018 | 2:00:00  |  109        |
 | 1033   | 6/25/2018 | 3:00:00  |  2642       |

与以前略有不同的粘性

我已经创建了一个Temp表-有关完整的解决方案，请参见[SQLFiddle] 1

我创建了如下的Grp和StartDate_Plus列

;WITH Numbers (Number) AS
(   SELECT ROW_NUMBER() OVER(ORDER BY N1.N) - 1
    FROM (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) N1(N)
    CROSS JOIN (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) N2 (N)
    CROSS JOIN (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) N3 (N)
    CROSS JOIN (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) N4 (N)
)
    SELECT
         D.UserId
        ,D.StartDate
        ,D.EndDate
        ,StartDate_Plus = DATEADD(HOUR, N.Number, D.StartDate) --Only for Ordering of ResultSet below
        ,N.Number
        ,Grp = MAX(N.Number)OVER(PARTITION BY UserId, StartDate)
    FROM
        dbo.T1  D
    INNER JOIN Numbers N ON N.Number <= DATEDIFF(HOUR, D.StartDate, D.EndDate)

像这样输出

UserId  StartDate                   EndDate                     StartDate_Plus              Number  Grp

StartDate_plus列仅将[小时数]添加到StartDate和Grp中，只是为了为同一事件提供一组多行

添加此额外的CTE，然后您可以在事件超过一个小时的每一小时显示假人StartDate_和EndDate_

        ,[StartDate_] = CASE --apply some rounding to the StartDate if required
                            WHEN Number = 0 THEN CS.StartDate
                            ELSE DATEADD(hour, DATEDIFF(HOUR, 0, CS.StartDate_Plus), 0)
                        END
        ,[EndDate_] =   CASE --apply some rounding to the EndDate if required
                            WHEN CS.Number = CS.Grp THEN CS.EndDate
                            WHEN CS.StartDate_Plus > CS.EndDate THEN CS.EndDate
                            WHEN CS.Number <> CS.Grp AND CS.StartDate_Plus <= CS.EndDate 
                                THEN DATEADD(HOUR, DATEDIFF(HOUR, 0, DATEADD(MINUTE, 30 + DATEPART(MINUTE, DATEADD(MINUTE, 30, CS.StartDate_Plus)),CS.StartDate_Plus)), 0) 
                        END
        ,[Hour] = CONVERT(TIME(0), DATEADD(HOUR, DATEPART(HOUR, CS.StartDate_Plus), 0))
    FROM
        cteStartDate_Plus CS
    ORDER BY
        UserId, CS.StartDate_Plus

然后将上面的查询封装到另一个名为CteDummyDates的CTE中，下面的查询只是为您提供所需的结果

SELECT
      UserId
     ,[Date] = CONVERT(DATE, DD.StartDate_Plus)
     ,DD.[Hour]
    ,[Seconds_in] = DATEDIFF(SECOND, DD.StartDate_, DD.EndDate_)
FROM
    cteDummyDates DD
ORDER BY
    DD.UserId, DD.StartDate_

输出

UserId  Date        Hour        Seconds_in
