Question

I have this simple code to select custom string from database:

protected function getListQuery()
{

              $db = JFactory::getDBO();
              $query = $db->getQuery(true);

              $query->select('*')
                    ->from('#__person');

              $name = 'tom';

              $query->where('name LIKE %'.$db->quote($name).'%');

              return $query;
} 

Unfortunately it gives me an error:

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean
given in xxx\public\libraries\joomla\database\database\mysql.php on
line 293

If I remove where call, so everything goes ok. Can I debug the datase query? I would like to see whats the final query goes to MySQL server.

Your help would be appreciated.

I’ve managed to work this for me:

protected function getListQuery()
{

    $db = JFactory::getDBO();
    $query = $db->getQuery(true);

    $query->select('*')
          ->from('#__person');

    $name = 'tom';

    $name = $db->Quote('%'.$db->escape($name, true).'%');
    $query->where($db->nameQuote('name').' LIKE '.$name);


    //debug the query  
    // echo nl2br(str_replace('#__','prefix_',$query)); die;

    return $query;

}
