You may try like this

query_posts('post_status=publish'); 
while (have_posts()) : the_post(); 
$id = get_the_ID(); 
$total_attachments = $wpdb->get_var("SELECT COUNT(*) FROM {$wpdb->prefix}posts WHERE post_type = 'attachment' AND post_parent=$id"); 
echo $total_attachments; 
endwhile; 
wp_reset_query();
