$db = JFactory::getDbo();$query = "INSERT INTO  #__pf_milestones  (`PRoject_id`,`title`)   VALUES (".$id.","."'".$title."'".")";$db->setQuery($query);$result = $db->query();return $result;        2 、簡易寫法（1）：

$db = JFactory::getDbo();$query = $db->getQuery(true); $query->insert('#__pf_milestones')->columns(array('project_id','title')); $values = array(); $values[]=$id; $values[]=$db->quote($title);  //轉化為字符串$query->values(implode(',',$values));$db->setQuery($query);$result = $db->query();return $result;  二、刪除記錄：

$db = JFactory::getDbo();$query = $db->getQuery(true);$query->delete('#__pf_task_power')

->where('project_id=' . $item[0]->project_id . ' AND milestone_id=' . $item[0]->milestone_id . ' AND user_id=' . $item[0]->id);

try {

$db->setQuery($query);

$db->execute();

$result = true;

} catch (Exception $e) {

$result = false;

}三、更新記錄：        $user = JFactory::getUser();        $db = JFactory::getDbo();        $query = $db->getQuery(true);        $query-> update('#__pf_milestones')                   -> set('is_transfer_upload=1')                   -> where('project_id='.$pro_id.' and created_by='.$user->id);        $db->setQuery($query);        $result = $db->query();        return $result;四、查找記錄：        $db = JFactory::getDbo();        $query = $db->getQuery(true);        $query-> select ("created_by")              -> from("#__pf_projects")              -> where("id=".$id);        $db -> setQuery($query);        $result = (array)$db->loadRowList();
