问题描述

我需要一点帮助.如何使用Codeigniter发送此查询?

I need a little help. How can i send this query with codeigniter?

Delete FROM friendconnect WHERE who = 5 and whos = 1 OR whos = 5 and who = 1;

我仅发现:

$this->db->where('id', $id);
$this->db->delete('mytable'); 

谢谢大家！

推荐答案

$this->db->where('who', 5);
$this->db->where('whos', 1);
$this->db->or_where('whos', 5);
$this->db->where('who', 1);

$this->db->delete('friendconnect');

这也是一种选择:

$this->db->where('who', 5)->where('whos', 1)->or_where('whos', 5)->where('who', 1);
$this->db->delete('friendconnect');

这也:

$this->db->where(array('who'=>5, array('whos'=>1)))->or_where('whos', 5)->where('who', 1);
$this->db->delete('friendconnect');
