create function dbo.concatvalues(@studentid int)
returns varchar(2000)
as
begin
  declare @res varchar(2000)
  select @res = coalesce( @res + ',' , '') + attribute
   from B where studentid = @studentid
  return @res
end

and use it like this:
select a.*, dbo.concatvalues(a.studentid) as attributes
from A
