  With cte_time

  As

  (Select 100 As event_id, '2012-11-29 06:00:00' As event_ts

  UNION ALL

  Select 200 As event_id, '2012-11-29 06:01:22' As event_ts

  UNION ALL

  Select 300 As event_id, '2012-11-29 06:01:49' As event_ts

  UNION ALL

  Select 600 As event_id, '2012-11-29 06:02:34' As event_ts

  UNION ALL

  Select 800 As event_id, '2012-11-29 06:05:19' As event_ts

  UNION ALL

  Select 900 As event_id, '2012-11-29 06:06:30' As event_ts

  UNION ALL

  Select 1000 As event_id, '2012-11-29 06:07:47' As event_ts

  UNION ALL

  Select 1100 As event_id, '2012-11-29 06:08:59' As event_ts

  )

  Select event_id, event_ts, 'x' As time_stamp_group

  From cte_time

  I want the 'x' to be replaced by a 5 minute grouping so that my final result looks like:

  event_idevent_tstime_stamp_group

  Try this

  Select event_id, event_ts, DATEADD(minute,(1+DATEDIFF(minute, 0, event_ts)/5)*5, 0) AS time_stamp_group

  From cte_time
