How are you handling the instance where he has entered twice but not exited between? ie: Rows 3 and 4.

This is raw data got from the access recorder , some times employee may aceess sometimes not i have to handle that also what to do

The point I am making is that you need to have a business rule that you can consistently apply to handle these situations. Without that rule to apply, you can't proceed past that point.

In case of the case here, he can take the last entry time and first exit time between multiple entries without recording and multiple exits without recording.
and can go for a stored proc to calculate tat.

Hi,
Follow the below steps:
1. Remove all blank spaces from AccessCardNo and EntryExit field (if any blank space)
Note: I just copy your provided table value and got blank space so remove them.

2. Execute the below query, it will give you Total Seconds stayed in office of a particular employee

SQL

select datediff(s,(SELECT TOP 1 RecordedTime AS Entry FROM tblTest Where AccessCardNo='0050' AND EntryExit='A0001'
ORDER BY RecordedTime ASC),(SELECT TOP 1 RecordedTime AS Out FROM tblTest Where AccessCardNo='0050' AND EntryExit='A0002'
ORDER BY RecordedTime DESC)) AS TotalSecondsInOffice

3. Keep the value in a variable

4. If you divide the result by 3600 then you will get hour
5. If you need Minute then divide the Remainder value by 60 then you will get Minute

Note: If you need only hour then run the below query

SQL

SELECT DATEDIFF(s,(SELECT TOP 1 RecordedTime AS Entry FROM tblTest Where AccessCardNo='0050' AND EntryExit='A0001'
ORDER BY RecordedTime ASC),(SELECT TOP 1 RecordedTime AS Out FROM tblTest Where AccessCardNo='0050' AND EntryExit='A0002'
ORDER BY RecordedTime DESC))/3600 AS TotalHoursInOffice

Thanks,
Mamun
