从Joomla 2.5中的表中选择时出现SQL语法错误

Question

I get this error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM lg3ni_k2_favorites AS faves, lg3ni_k2_items AS items, WHERE (faves.user' at line 1 SQL=SELECT faves.item_id AS item_id, items.title AS items_name, FROM lg3ni_k2_favorites AS faves, lg3ni_k2_items AS items, WHERE (faves.user_id='349') AND (faves.item_id = items.id)

From the syntax:

$db =& JFactory::getDBO();

    $query = "SELECT faves.item_id AS item_id, items.title AS items_name, ";
    $query .= "FROM `#__k2_favorites` AS faves, `#__k2_items` AS items, ";
    $query .= "WHERE (faves.user_id='".intval($userID)."') ";
    $query .= "AND (faves.item_id = items.id) ";

    $db->setQuery($query);
    $ff = $db->loadObjectList();
    echo $db->getErrorMsg();
    return $ff; 

Where is the problem?

Answer 1

You have an extra comma after items_name, ,another extra comma after AS items

 $query = "SELECT faves.item_id AS item_id, items.title AS items_name ";
 $query .= "FROM `#__k2_favorites` AS faves, `#__k2_items` AS items ";

Answer 2

remove comma from both below queries

$query = "SELECT faves.item_id AS item_id, items.title AS items_name ";
    $query .= "FROM `#__k2_favorites` AS faves, `#__k2_items` AS items ";

Answer 3

Try using the following:

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

$query->select($db->quoteName('faves.item_id') . ' AS ' . $db->quoteName('item_id') . ',' . $db->quoteName('items.title') . ' AS ' . $db->quoteName('items_name')))
      ->from($db->quoteName('#__k2_favorites') . ' AS ' . $db->quoteName('faves') . ',' . $db->quoteName('#__k2_items') . ' AS ' . $db->quoteName('items'))
      ->where($db->quoteName('faves.user_id') . ' = '. $db->quote(intval($userID)) . ' AND ' . $db->quoteName('faves.item_id') . ' = '. $db->quote('items.id'));     
$db->setQuery($query);

$ff = $db->loadObjectList();

This uses Joomla coding standards, however please note that I haven't tested it so let me know if it works or not.
