尝试简单的方法：-

$db = JFactory::getDbo();
$query = 'SELECT data FROM #__gztqw_team_member_datadetails WHERE profile_key LIKE "custom.%" order by ASC';
$db->setQuery($query);
$results = $db->loadObjectList();

此外，您还没有在函数中恢复任何值，并且在哪里显示它是在视图中显示数据的最佳方式，使用控制器功能并分配结果值以在视图中显示

你需要阅读http://docs.joomla.org/Developing_a_Model-View-Controller_%28MVC%29_Component_for_Joomla!2.5

首先，您视图中的类称为HelloWorldViewHelloWorld，它应该称为Team_memberViewTeam_member，这就是导致您的错误的原因。

其次，理想情况下，您应该将数据库查询放入您的模型中，但是如果您将其放入您的视图中，它仍然可以工作。我已经为您提供了一个示例，说明如何使其与视图中的查询一起使用。我创建了一个名为 $items 的受保护变量，并将数据库中的结果分配给该变量。

在您的模板中，您将使用以下方式访问数据库中的数据

foreach($this->items as $item):
       echo $item->id;
endforeach();

在你看来你应该有

class Team_memberViewTeam_member extends JView
{
    protected $items;

    // Overwriting JView display method
    public function display($tpl = null) 
    {
         $db = JFactory::getDbo();

           // Create a new query object.
            $query = $db->getQuery(true);

     // Select all records from the user profile table where key begins with "custom.".
// Order it by the ordering field.
        $query->select(array('id', 'member_name', 'member_pic','member_des','member_description'));
        $query->from('#__gztqw_team_member_datadetails');
        $query->where('profile_key LIKE \'custom.%\'');
        $query->order('ordering ASC');

  // Reset the query using our newly populated query object.
        $db->setQuery($query);

// Load the results as a list of stdClass objects.
        $this->items = $db->loadObjectList(); 
         parent::display($tpl);
    }
}
