update 有错误么？各位帮忙看一下

Gawie

$this->db->update('article',array('title' => '123'),array('aid'=>'16'));

一直报错：

A Database Error Occurred

You must use the "set" method to update an entry.

Filename: F:\phpServer\phpnow\htdocs\aiyuedu\system\database\DB_active_rec.php

Line Number: 1272

使用这样的写法，也报错

$this->db->set(array('title' => '123'));
$this->db->where(array('aid'=>'16'));
$this->db->update('article');
