use strict;
use DBI;
my ($dbh, $sth, $prm);
$prm = 5;
$dbh = DBI->connect(qq{DBI:CSV:csv_sep_char=\\;;csv_eol=\n});
$dbh->{'csv_tables'}->{'agents'} = { 'file' => 'agents.csv'};
$sth = $dbh->prepare("update agents set id = id + ?");
$sth->execute($prm) or die "Cannot execute: " . $sth->errstr();
$sth->finish();
$dbh->disconnect();
