Hi,
I don't use MYSQL, but the problem is common for
databases. One of the idea of auto increment field is
to have unique identifiers, so you can't insert a
record with auto increment fields set by yourself.
It's always done by DB. So you can't fill a "hole" in
numbering after deleting record. Of course in a normal
way of using DB... :-)
