How do you insert data into the table of a database in Oracle in Perl?

use DBI;

$oracle_server = 'localhost';
$oracle_user = '<UserName>';
$oracle_passwd = '<Password>';
$oracle_sid = 'ORCL';
$oracle_table = 'PerlDB';
$oracle_port = '1521';

$dbh = DBI->connect("dbi:Oracle:host=$oracle_server; port=$oracle_port; sid=$oracle_sid", $oracle_user, $oracle_passwd, { RaiseError => 1, AutoCommit => 0}) or die "$DBI::errstr\n";

my $sql = "INSERT INTO $oracle_table (EMP_NUM, EMP_NM, JOB, MNGR_ID, SAL) VALUES (?, ?, ?, ?, ?)";

my $rv = $dbh->do($sql, undef, 21295, 'RABINDRA', 'PROGRAMMER', 7839, 8000) or die "$DBI::errstr";
$dbh->disconnect();
