Replacing CURSORS in SQL server

the below first part of the code is displaying( printing) top 5 roleNames from a table and it is using CURSORS to looping thru each record

	declare @RoleName nchar(15)
	declare @RowNum int
	declare RoleList cursor for
	select top 5 rolename from luRole
	OPEN RoleList
	FETCH NEXT FROM RoleList INTO @RoleName
	set @RowNum = 0 
	
	WHILE @@FETCH_STATUS = 0
	BEGIN
	  set @RowNum = @RowNum + 1
	  print cast(@RowNum as char(1)) + ' ' + @RoleName
	  FETCH NEXT FROM RoleList INTO @RoleName
	END
	CLOSE RoleList
	DEALLOCATE RoleList

 GO

Cursor can degrade the performnace of the query. So better to make use of the WHILE loop and the below query will results the same output as above... For simpliying the logic i used only printing top 5 records from the table.

	declare @RoleName nchar(30), @RoleId int
	declare @RowNum int
	select top 1 @RoleName=RoleName, @RoleId = RoleID from dbo.luRole ORDER BY RoleID
	set @RowNum = 0 
	WHILE @RowNum < 5
	BEGIN
	  set @RowNum = @RowNum + 1
	  print cast(@RowNum as char(1)) + ' ' + @RoleName
	  select top 1 @RoleName=rolename from dbo.luRole
	               where roleID > @RowNum
	END
