Here's a slightly different approach - I create a load of SQL statements, put them in an array,

foreach my $sql (@sql) {
       unless ($sth=run_sql($sql)){
            die "Failed in processing \"".$sql."\"\n";
    }
}
#Use them like this...
my $result = $sth->fetchall_arrayref;

and then run them using this subroutine -

#
#run_sql
# subroutine that does all of the work
#
sub run_sql{
my $sql = shift;

    my $sth = $dbh->prepare($sql);
      if (!$sth) {
          die "Error:" . $dbh->errstr ." while preparing ".$sql."\n";
      }

      if (!$sth->execute) {
          die "Error:" . $sth->errstr ." while executing ".$sql."\n";
      }

return $sth;
} # run_sql

The idea here is that I like to pass statement handles around ($sth), which I can then do whatever I want with. I find this much more flexible than passing result sets around. YMMV!
