将网站更新为CodeIgniter 3后，出现此错误
我的代码：
public function get_pickedItems(){
$this->db->select('p.user_id,u.user_name,u.email,u.full_name,u.thumbnail,u.address,u.phone_no,u.postal_code,u.state,u.country,u.city');
$this->db->from(USER_PAYMENT.' as p');
$this->db->join(USERS.' as u' , 'p.user_id = u.id');
$this->db->join(PRODUCT.' as pd' , 'pd.id = p.product_id');
$this->db->where('p.user_id > 1 GROUP BY p.user_id');
$this->db->order_by('p.id','ASC');
return $this->db->get();
}
错误

我更改的唯一与数据库相关的东西是config / database.php文件。
由于3.0.0将Active Record重命名为Query Builder，因此在config / database.php中，您需要将$ active_record变量重命名为$ query_builder
$active_group = 'default';
// $active_record = TRUE;
$query_builder = TRUE;
