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;

I found only that:

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

Thanks everybody!


回答1:


$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');

This is also an alternative:

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

This also:

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

Just use this $this->db->query("Delete FROM friendconnect WHERE who = 5 and whos = 1 OR whos = 5 and who = 1");




回答3:


$this->db->where('(who = 5 and whos = 1) OR (whos = 5 and who = 1)');
$this->db->delete('friendconnect');
