I'll just comment on this part for now:
my $sth = $dbh->prepare($sql, { RaiseError => 1 });
   $sth->execute() or die "$!\n";

RaiseError should really be in the connect() call. If it is, then you don't need all the "or die ..." on every DBI method. But if you don't use RaiseError and you do say "or die ..." on every DBI method, then $! is the wrong variable to use in the error message, it should be $DBI::errstr.
