Transitioning to PDO/MySQL. Need help with SELECT statement.

How do I transition this select statement to PDO with PHP?

$result1 = mysql_query("SELECT * FROM `product_description`");
while($row1 = mysql_fetch_assoc($result1))
{


mysql_query("INSERT INTO `product_description` (`product_id`, `name`, `description`, short_description) VALUES ('".mysql_real_escape_string($row1['product_id'])."','".mysql_real_escape_string($row1['name'])."','".mysql_real_escape_string($row1['description'])."','".mysql_real_escape_string($row1['short_desc'])."')");


}

<?php
$database_name = "";
$username = "";
$password = "";

$conn = new PDO('mysql:host=localhost;dbname='.$database_name, $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

// Get rows
$result = $conn->query("SELECT * FROM `product_description`");

// Prepare the update sql
$do_update = $conn->prepare("INSERT INTO `product_description` (`product_id`, `name`, `description`, `short_description`)
VALUES (:product_id, :name, :description, :short_desc)");

while ($row = $result->fetch(PDO::FETCH_ASSOC)){
{

	// Execute the update for each row
	$do_update->execute(array(
		':product_id'	=>	$row['product_id'],
		':name'		=>	$row['name'],
		':description'	=>	$row['description'],
		':short_desc'	=>	$row['short_desc']
	));

Here's an article covering most of the aspects of the conversion.
http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/PHP_Databases/A_11177-PHP-MySQL-Deprecated-as-of-PHP-5-5-0.html

In the case of the SELECT statement, there are no changes needed at all.  Things only change when you use external variables as part of the query.  The article explains why and shows a few ways of making the transition from direct variable injection (into the query string) and indirect injection via parameterized queries or placeholders.
