Select Sum HH:MM for period between two dates - sql

Question

I would like to get the sum of hours (Duration) worked between say 16/11/2016 09:00 > 15/12/2016 17:30. To achieve this I need to calculate the Duration for each day worked between the two dates and then to add those up to get monthly hours worked.
The EventTime table will contain data for every time a user clock in when they start work, clocks out at lunch time, clocks back in after lunch, and then clocks out at the end of the day.
I have managed to get this to work for a single day:
EMPLOYEE CLOCK IN CLOCK OUT DURATION

The above is achieved using the following query:
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
I hope that is clear.
Thanks in advance.
Update: 06/01/2017
I am able to use the following query:
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
to get this result:

Now how can I get the MIN and MAX for each user for each day from that result set (as below)?
Employee Clocked In Clocked Out Duration
Ram 16/11/2016 09:12 16/11/2016 17:47 08:35
Ram 17/11/2016 09:35 17/11/2016 17:43 08:08
...
Ram 13/12/2016 09:13 13/12/2016 18:01 08:48
Ram 15/12/2016 09:07 15/12/2016 17:53 08:46
and so on for each employee...

Answer 1

Convert each Duration field to seconds and then add it to the format HH:MM
This is an example:
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
RESULT
seconds seconds to HH:MM

One option to implement in your query this solution would be to use a CTE. In this case with a CTE would look something like this:
;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
UPDATED
According to your update, you would need to query using the MIN and MAX aggregate functions, but performing a GROUP BY for dates converted to DATE. With this you can get the highest and lowest value for each day.
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
Then, you only need to sum the seconds and convert them to the HH:MM format that I showed you, using the CTE or a Subquery.
