Erm - it has been in, ah, abeyance for some months, owing to lack of interest in meetings. However, the recent return of Grant McLean strikes me as an excellent opportunity to revive meetings. Takers, anyone?

I think the one you're using for MySQL will work. MySQL is supposed to be compatible with mSQL at a binary level.

If you're going to do more with DBI, invest in this:

Well worth it. Dymocks or Capital Books probably have a copy in stock.

Yes, that should work Just Fine. It's been a while, but I think you can reuse your statement handle too:

my $sth;
foreach my $query (@queries) {
     $sth = $dbh->prepare($query);
     $sth->execute();
}
$sth->finish();

which might speed things up in a nested loop more than somewhat.
