Thanks for all of the help. I appologize because I should have actually said $dbh->{'mysql_insertid'}, sorry for the confusion. What I ended up doing is writting a quick function to look at the table and return the first auto_increment field it found.

This is what I came up with: 
sub get_auto_increment {
    my ($dbh, $table) = @_;

    my $sth = $dbh->prepare("show columns from $table");
    $sth->execute;

    my $ref;
    while ($ref = $sth->fetchrow_hashref) {
        if ($ref->{'Extra'} eq 'auto_increment') {
            $sth->finish;
            return $ref->{'Field'};
        }
    }

    $sth->finish;
    return undef;
}

The idea is that the first column that matches 'auto_increment' will be the column that $dbh->{'mysql_insertid'} is referring to. I am not sure what the rules are for mysql's auto_increment definition. If I am not mistaken (which I probably am) all columns marked auto_increment would get the same value anyway?

Thanks,
