Hello

There is something more to do.

Hint: First add a column to your table which simply indicates present and absent booking timestamps. Below is an example of a table with computed column isPresent and ordered by PersonalNumber what I had already published elsewhere:

/*
PersonalNumber  BookingStamp             isPresent
--------------------------------------------------
1000            2009-08-11 07:12:05.000  1
1000            2009-08-11 09:10:00.000  0
1000            2009-08-11 10:08:29.000  1
1000            2009-08-11 18:31:01.000  0
2000            2009-08-11 08:56:00.000  1
2000            2009-08-11 19:00:00.000  0
2000            2009-09-09 09:08:07.000  1
2000            2009-09-09 15:18:00.000  0
3000            2009-08-10 07:30:05.000  1
3000            2009-08-10 17:00:57.000  0
3000            2009-08-11 12:12:12.000  1
*/

If this additional column is given, selecting present and absent booking timestamps in same row together with corresponding personal number can simply be achieved by various methods depending on database.
