I would but then I don't know how to ensure I return that exact same
id from the insert, like mysql_insert_id() does. That's the whole
reason why I aquire the id first, so I know what it is after the
insert. SELECT max(id) would be off under load I think.
I just didn't understand why it appeared to be +2 and not +1 as a
novice might expect. But now I get it. Thanks to all.
