I'm Trying to calculate the total worked hours by employee:
My table "Log_Attendance" like this

CSS

EnrollNumber       InOutMode       DateAttendance       TimesInOut
27                   0              07-09-2015           07-09-2015 08:00:00
27                   2              07-09-2015           07-09-2015 10:00:00
27                   3              07-09-2015           07-09-2015 11:00:00
27                   1              07-09-2015           07-09-2015 12:00:00
27                   0              07-09-2015           07-09-2015 13:00:00
27                   1              07-09-2015           07-09-2015 17:00:00

InOutMode-->  0:CheckIn     1: CheckOut         2:BreakIn        3:BreakOut

I need to calculate only the worked hours!
example:

EnrollNumber       TotalWorkedHours
27                       7    (=(10-8)+(12-11)+(17-13))

Any Solution please

If I understand correctly, you need to fetch a row for in and for out and to calculate the difference?

If so, perhaps something like:

SQL

SELECT DATEDIFF(hour, out. TimesInOut, in.TimesInOut)
FROM Log_Attendance in,
     Log_Attendance out
WHERE in.enrollnumber = out.enrollnumber
AND   in.inoutmode = 0
AND   out.inoutmode = 1
AND   in.DateAttendance = out.DateAttendance
...

Of course that's not the whole logic but it'll jopefully get you started...

thanks for your reply but it gives me wrong value !!

As said, the conditions are not complete. You need to add possibly missing logic for example what about inoutmodes 2 and 3.

What the example should do is to give you few of the rows and idea how the query could be built.
