Есть ли простой скрипт для переноса из доп поля в столбец?

<?
	define('DATALIFEENGINE', true);
	define('LOGGED_IN', true);

	$db_name = "actor";
	$xf_name = "dop_pole";
	
	define('ROOT_DIR', dirname (__FILE__));
	define('ENGINE_DIR', ROOT_DIR.'/engine');
	require_once ENGINE_DIR.'/classes/mysql.php';
	require_once ENGINE_DIR.'/data/dbconfig.php';
	
	require_once ENGINE_DIR.'/inc/include/init.php';
	
	$count = $db->super_query("SELECT count(*) as count FROM ".PREFIX."_post WHERE xfields != ''");
	$sql = $db->query("SELECT id, xfields FROM ".PREFIX."_post WHERE xfields != '' LIMIT 0,{$count['count']}");

	while ($row = $db->get_row($sql)){
	
		$xfieldsdata = xfieldsdataload($row['xfields']);
		$name = $xfieldsdata[$xf_name];
	
		$db->query("UPDATE ".PREFIX."_post SET {$db_name} = '{$name}' WHERE id = '{$row['id']}'");
	}
	echo "Успешно"
?>
