Grouping rows with a date range

A Left Outer Join and DateDiff Function should help you to filter the records. Finally Use Window Function to create GroupID's

create table #test 

INSERT #test
VALUES ( 1,9,'2014-10-12 00:00:00','2014-10-13
       (2,9,'2014-10-14 14:00:00','2014-10-15
       (3,9,'2014-10-16 14:00:00','2014-10-17
       (1,10,'2014-10-16 14:00:00','2014-10-17
       (2,10,'2014-10-18 14:00:00','2014-10-19

SELECT Row_number()OVER(partition by a.WH_PID
FROM   #test a
       LEFT JOIN #test b
              ON a.WH_PID = b.WH_PID
                 AND a.ADM_ID <> b.ADM_ID
where  Datediff(hh, a.WH_OUT_DATETIME,


Group_Id    WH_PID  WH_IN_DATETIME

2014-10-15 15:00:00.000
