php - Access Joomla 2.5 from external script to get article by id

I like to read an article by id from Joomla 2.5. As I'm not inside the framework I've to include it first. I found also some samples how to get an article by id than but it ever fails ... This is the sample I'm trying:

define( '_JEXEC', 1 );
define( '_VALID_MOS', 1 );
define( 'JPATH_BASE', realpath(dirname(__FILE__)));
define( 'DS', DIRECTORY_SEPARATOR );
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
echo JPATH_BASE .DS.'includes'.DS.'framework.php';
$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
echo  $mainframe->getCfg('sitename');

$articleId = JRequest::getInt('Itemid');
$db =& JFactory::getDBO();

$sql = "SELECT fulltext FROM #__content WHERE id = 260"; //.intval($articleId);
$db->setQuery($sql);
$fullArticle = $db->loadResult();

Article ID 260 is available but it ever return null ...

When I trace it $cursor in loadResult() is every null:

public function loadResult()
{
    // Initialise variables.
    $ret = null;

    // Execute the query and get the result set cursor.
    if (!($cursor = $this->execute()))
    {
        return null;
    }
     ...

Can somebody help please?

Thanks Andre

There are a few things you don't need in your script and I have changed it to Joomla 2.5 coding standards:

define('_JEXEC', 1);
define('JPATH_BASE', realpath(dirname(__FILE__)));
require_once ( JPATH_BASE .'/includes/defines.php' );
require_once ( JPATH_BASE .'/includes/framework.php' );
require_once ( JPATH_BASE .'/libraries/joomla/factory.php' );

$db = JFactory::getDBO();
$query = $db->getQuery(true);
$query->select('introtext')
 ->from('#__content')
 ->where('id = 260');
$db->setQuery($query);

$fullArticle = $db->loadResult();

echo $fullArticle;

Hope this helps
