选择Sum HH：MM两个日期之间的时间段

标签： sql sql-server database tsql

我想知道16/11/2016 09:00＆gt;之间工作的小时数（持续时间）。 2016/12/15 17:30为了实现这一点，我需要计算两个日期之间每天工作的持续时间，然后将这些日期添加到每月工作时间。

EventTime表将包含用户每次开始工作时的时钟数据，午餐时间时钟，午餐后时钟，然后在当天结束时退出。

我设法让这一天工作了一天：

Ana         05/01/2017 07:41    05/01/2017 14:13    06:32

使用以下查询实现上述目的：

SELECT
    u.Field14_50 AS EmployeeID,
    u.Firstname,
    u.Surname,
    MIN(e.EventTime) AS [Clocked In],
    CASE 
        WHEN MAX(e.EventTime) = MIN(e.EventTime) THEN NULL
        WHEN MAX(e.EventTime) > MIN(e.EventTime) THEN MAX(e.EventTime)
    END AS [Clocked Out],
    CASE
        WHEN MAX(e.EventTime) = MIN(e.EventTime) THEN NULL
        WHEN MAX(e.EventTime) > MIN(e.EventTime) THEN FORMAT((DATEDIFF(SECOND, MIN(e.EventTime), MAX(e.EventTime)) / 3600) % 24,  '00') + ':' + FORMAT((DATEDIFF(SECOND, MIN(e.EventTime), MAX(e.EventTime)) / 60) % 60, '00')
    END AS [Duration]
FROM
    UsersEx AS u
INNER JOIN
    EventsEx AS e
ON
    u.UserID = e.UserID
WHERE
    u.Field14_50 <> ''
AND
    u.DepartmentName IN (
        'Production',
        'Finance and Administration',
        'Purchase',
        'Sales',
        'Warehouse'
    )
AND
    DAY(e.EventTime) = DAY(GETDATE())     AND     MONTH(e.EventTime) = MONTH(GETDATE())      AND     YEAR(e.EventTime) = YEAR(GETDATE())
AND
    e.PeripheralName IN ('TIME AND ATTENDANCE OFFICE (In)', 'TIME AND ATTENDANCE OFFICE (Out)')
GROUP BY
    u.Field14_50,
    u.UserID,
    u.FirstName,
    u.Surname
ORDER BY
    u.Surname ASC

我希望这很清楚。

提前致谢。

我可以使用以下查询：

SELECT
    u.FirstName,
    e.EventTime
FROM
    UsersEx AS u    
INNER JOIN
    EventsEx AS e
ON
    u.UserID = e.UserID
WHERE
    u.Field14_50 <> ''
AND
    e.EventTime > '2016/11/16'     AND     e.EventTime < '2016/12/16'
AND
    e.PeripheralName IN ('TIME AND ATTENDANCE OFFICE (In)', 'TIME AND ATTENDANCE OFFICE (Out)')
AND
    u.DepartmentName IN ('Finance and Administration')
ORDER BY
    u.Field14_50,
    e.EventTime
ASC

得到这个结果：

and so on for each employee...

将每个持续时间字段转换为秒，然后将其添加为 HH：MM

格式

这是一个例子：

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

CREATE TABLE #tmp (
    Id INT IDENTITY
    , duration VARCHAR(MAX)
    )

INSERT INTO #tmp (duration)
VALUES ('04:39')
    , ('03:20')
    , ('05:59')

SELECT 
    Sum(Left(duration, 2) * 3600 + substring(duration, 4, 2) * 60) AS seconds
    , CONVERT(VARCHAR, DATEADD(ms, (Sum(Left(duration, 2) * 3600 + substring(duration, 4, 2) * 60)) * 1000, 0), 114) AS 'seconds to HH:MM'
    --http://stackoverflow.com/questions/1262497/how-to-convert-seconds-to-hhmmss-using-t-sql
FROM #tmp

DROP TABLE #tmp

<强> RESULT 

seconds     seconds to HH:MM

在您的查询中实施此解决方案的一个选项是使用 CTE 。在这种情况下，CTE看起来像这样：

;WITH Base
AS (
    SELECT u.Field14_50 AS EmployeeID
        , u.Firstname
        , u.Surname
        , MIN(e.EventTime) AS [Clocked In]
        , CASE 
            WHEN MAX(e.EventTime) = MIN(e.EventTime)
                THEN NULL
            WHEN MAX(e.EventTime) > MIN(e.EventTime)
                THEN MAX(e.EventTime)
            END AS [Clocked Out]
        , CASE 
            WHEN MAX(e.EventTime) = MIN(e.EventTime)
                THEN NULL
            WHEN MAX(e.EventTime) > MIN(e.EventTime)
                THEN FORMAT((DATEDIFF(SECOND, MIN(e.EventTime), MAX(e.EventTime)) / 3600) % 24, '00') + ':' + FORMAT((DATEDIFF(SECOND, MIN(e.EventTime), MAX(e.EventTime)) / 60) % 60, '00')
            END AS [Duration]
    FROM UsersEx AS u
        INNER JOIN EventsEx AS e
            ON u.UserID = e.UserID
    WHERE u.Field14_50 <> ''
        AND u.DepartmentName IN (
            'Production'
            , 'Finance and Administration'
            , 'Purchase'
            , 'Sales'
            , 'Warehouse'
            )
        AND DAY(e.EventTime) = DAY(GETDATE())
        AND MONTH(e.EventTime) = MONTH(GETDATE())
        AND YEAR(e.EventTime) = YEAR(GETDATE())
        AND e.PeripheralName IN (
            'TIME AND ATTENDANCE OFFICE (In)'
            , 'TIME AND ATTENDANCE OFFICE (Out)'
            )
    GROUP BY u.Field14_50
        , u.UserID
        , u.FirstName
        , u.Surname
    --ORDER BY u.Surname ASC --Don't include ORDER BY here.
    )
SELECT CONVERT(VARCHAR, DATEADD(ms, (Sum(Left(duration, 2) * 3600 + substring(duration, 4, 2) * 60)) * 1000, 0), 114) AS 'sum of hours (Duration)'
FROM Base
ORDER BY u.Surname

<强>已更新

根据您的更新，您需要使用 MIN 和 MAX 汇总功能进行查询，但为日期<执行 GROUP BY em>转换为DATE 。有了它，您可以获得每天的最高和最低价值。

<强> CODE： 

SELECT u.FirstName
    , MIN(e.EventTime) AS 'Clocked In'
    , CASE 
        WHEN MIN(e.EventTime) = MAX(e.EventTime)
            THEN NULL
        ELSE MAX(e.EventTime)
        END AS 'Clocked Out'
    , DATEDIFF(SECOND, min(e.EventTime), MAX(e.EventTime)) AS 'Duration in seconds'
    , CONVERT(VARCHAR, DATEADD(ms, DATEDIFF(SECOND, min(e.EventTime), MAX(e.EventTime)) * 1000, 0), 114) AS 'Duration'
FROM UsersEx AS u
    INNER JOIN EventsEx AS e
        ON u.UserID = e.UserID
WHERE u.Field14_50 <> ''
    AND e.EventTime > '2016/11/16'
    AND e.EventTime < '2016/12/16'
    AND e.PeripheralName IN (
        'TIME AND ATTENDANCE OFFICE (In)'
        , 'TIME AND ATTENDANCE OFFICE (Out)'
        )
    AND u.DepartmentName IN ('Finance and Administration')
GROUP BY u.FirstName
    , cast(e.EventTime AS DATE)
ORDER BY u.FirstName

然后，您只需要将秒数相加并将它们转换为我向您展示的HH：MM格式，使用 CTE 或子查询。
