example:
date_entry time_start time_finished idle_code
8/8/2013 8:00 9:00 0
8/8/2013 9:01 10:00 1
8/8/2013 11:01 12:00 2
8/8/2013 12:01 13:00 3
8/8/2013 13:01 14:00 4
8/8/2013 14:01 15:00 5
8/8/2013 16:01 17:00 6
8/8/2013 17:01 18:00 7
how can i combine/group the idle_code '0' and 6 then the other group idle_code '1','2','3','4','5','7'
i only need to groups group A = '0', '6' and group B = '1','2','3','4','5','7'
