#!/usr/bin/perl -w
use strict;
use DBI;

my $driver = 'mysql';
my $database = 'trainXX';
my $username = 'trainXX';
my $password = 'your_password_here';

my $dsn = "DBI:$driver:database=$database";
my $dbh = DBI->connect($dsn, $username, $password) 
        || die $DBI::errstr;

my $sql_statement = "select * from stock_item";
my $sth = $dbh->prepare($sql_statement);
$sth->execute() or die ("Can't execute SQL: " . $dbh->errstr());

while (my @ary = $sth->fetchrow_array()) {
        print <<"END";
ID:            $ary[0]
