You don't really provide enough information to allow for a complete answer. However, given that you have an ID, you probably want to check out the DESC keyword. Something like:

SELECT whatever FROM table ORDER BY id DESC;

The results will be sorted in descending (or reverse) order. See http://www.mysql.com/doc/S/o/Sorting_rows.html for more information.

If things get any worse, I'll have to ask you to stop helping me.
