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)')
