Answer 1

Try This: replace with name of your table

select a.ticketno
        ,a.CreateDate as [AssignedToTom]
        ,b.CreateDate as [AssignedToJerry]
         from <tablename> a join <tablename> b 
         on a.assigned='Tom' and b.assigned='Jerry' 
         and a.ticketno=b.ticketno

Answer 2

Try Below Pivot Query. Simply replace table name '#temp' to Your 'table name'

            select distinct  TicketNo,Tom as AssignedToTom,Jerry as AssignedToJerry
            from
            (
               select distinct TicketNo,CreateDate,Assigned 
               from #temp
            ) src
            pivot
            (
              max(CreateDate)
              for Assigned in (Tom, Jerry)
            ) piv

select ticketno,
