The lack of $dbh->disconnect is a potential disaster waiting to happen. Don't know what the SQL server defaults are but by default MySQL will accept 100 connections that will persist for 8 hours. Although it surprised me undefing $dbh (ie when the script finishes) does not cause a DESTROY{ ..disconnect .. ) to be called allowing the connections to persist and accumulate.....until it falls over with a too many connections error. This particular error often goes unnoticed until you get real load on a widget.

One way to code it to make sure this does not happen is 

my $sth;
my $dbh->connect(......
END{ $sth->finish if $sth; $dbh->disconnect if $dbh }

# now do whatever
