  Calculating Difference between ClockIn and ClockOut by Job.

  Table : JobTran

  Job# ClockIn ClockOut

  ---------------------------------------------------------------------

  Job1 2013-10-03 06:17:34.387 NULL

  Job1 2013-10-03 05:17:34.387 2013-10-03 08:10:34.387

  Job2 2013-10-03 09:17:34.387 2013-10-03 10:05:34.387

  Job2 2013-10-03 09:17:34.387 NULL

  if the ClockOut is NULL I would use GETDATE() to calculate the difference between ClockIn and ClockOut

  Assuming GETDATE() is 2013-10-03 11:15:34.387

  Job1 - 7.92 total hours (4.96 from 1st record, 2.96 from second record )

  Job2 - 2.76 total hours (0.8 from 1st record, 1.96 from second record )
