Answer 1

You can coalesce your NULLs in the ORDER BY statement:

select * from tablename
where 
order by
    coalesce(position, 0) ASC, 
    id DESC

If you want the NULLs to sort on the bottom, try coalesce(position, 100000). (Make the second number bigger than all of the other position's in the db.)
