codeigniter - 不等于 Codeigniter 事件记录中的比较

Question

我对这个代码收到的错误感到很困惑

$this->db->order_by('uid','DESC')->where('type!=',"Admin")->get('user_profile',$config['per_page'], $this->uri->segment(3));

这是我得到的错误

Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL      server version for the right syntax to use near ''Admin' ORDER BY `uid` DESC LIMIT 10' at line 3

SELECT * FROM (`user_profile`) WHERE `type!=` 'Admin' ORDER BY `uid` DESC LIMIT 10

Answer 1

像这样尝试你的查询。 Admin 使用单逗号而不是双逗号。和 <> 而不是 !=

$this->db
    ->where('type <>','Admin')
    ->order_by('uid','DESC')
    ->get('user_profile',$config['per_page'], $this->uri->segment(3));
