将以下MySQL查询转换为Codeigniter等效项

Question

I'm very new to CodeIgniter and I have some problem converting MySQL queries to CodeIgniter. I want to update a record in one table with condition on another relational table.

Following is my MySQL query

UPDATE `user` SET `securitytoken` = '71b9b5bc1094ee6eaeae8253e787d654'
WHERE `profileid` IN (SELECT pid FROM `profile` WHERE `email` = 'username@mail.com')    

This works fine in phpMyAdmin, but I wanted the same to be converted to codeigniter update query. Can anyone help me to convert.

I'm using CI v3.0.3 in Local WAMP Server.

Thanks in Advance

Answer 1

What I would do is code your query as is using

$query = $this->db->query('YOUR QUERY HERE');

and use the escape capabilities to take care of your one or two input values.

Pay attention to query bindings, may be useful in your case.

See: http://www.codeigniter.com/user_guide/database/queries.html

I would not try to use Active Records, your SQL is a bit too complex for that.

Answer 2

Try this

$query = $this->db->query("UPDATE `user` SET `securitytoken` = '71b9b5bc1094ee6eaeae8253e787d654'
WHERE `profileid` IN (SELECT pid FROM `profile` WHERE `email` = 'username@mail.com')");
$result = $query->result_array();
return $result;

Answer 3

$query=$this->db->query("SELECT pid FROM `profile` WHERE `email` = 'username@mail.com'")->row_array();

$this->db->set(`securitytoken`,'71b9b5bc1094ee6eaeae8253e787d654');
$this->db->where_in(`profileid`,$query['pid']);
$this->db->update('user');

//echo $this->db->last_query();
//exit;

Try this...!
