Except when your primary key value rolls over, or fills a gap between
two other rows that was left when a row was deleted/moved/etc... there
has got to be a better way than grabbing rows in descending order
based on the auto_increment value.
Are you doing the inserts one at a time? If so, why not just use code
to remember what you put in the DB?
