I tried to show my prefix but I can't display it. It just shows a white page.

define( 'INVOICE', dirname(__FILE__) );
global $wpdb;
include INVOICE . '/invoice.php';
$id= $_GET['id'];
$query= "Select * from '$table' where id='$id'";
echo $wpdb->prefix;

The prefix is what adds "wp-" to a custom table. Are you trying to query a table and get results back?
