Well, my comment on this is that the autoincrement field is giving you a
primary key which is not changing, and this is good. Check the scripts you
used to build the tables, and your MySQL docs for the MyISAM table type.
When tables are defined as being of the type MyISAM, the autoincrement
numbers don't change. In the newer versions of MySQL that may be the
default and you will have to add tell MySQL to NOT use this table type.
I don't know why you want to do this, as an unchanging, and really
simple-to-implement primary key is a very useful feature, particularly as
you can any sort order you desire in your SELECT statement.
