CI框架調(diào)用MySQL的存儲(chǔ)過(guò)程，可以返回結(jié)果，但是不能渲染到模板。報(bào)錯(cuò)如下：Error Number: 2014Commands out of sync; you can't run this command now這是什么原因呢？代碼如下：$common = $this->db->query("call welcome_common_data($role_id)");$data['head_data'] = $common->result_array()[0];$this->view('/welcome/test',$data);
