Answer 1

declare @S varchar(50)
set @S = 'John Roshan 2000'

;with cte as
(
  select 
    1 as P1,
    charindex(' ', @S+' ', 1) as P2
  union all
  select
    C.P2+1,
    charindex(' ', @S+' ', C.P2+1) as P2
  from cte as C
  where charindex(' ', @S+' ', C.P2+1) > 0
)

select
(
  select substring(@S, P1, P2-P1)+' '
  from cte
  order by substring(@S, P1, P2-P1)
  for xml path(''), type
).value('.', 'varchar(50)')
