Q:

Disable timestamp update in codeigniter

Faced the problem: when i am trying to update field via active record in CodeIgniter there also updates timestamp field. For example my code:
$this->db->where('user_i', 1);
$this->db->update('ci_users', $user_info);

Creates this sql:
UPDATE `ci_users` SET `user_fullname` = 'asdasdfsafd' WHERE `user_iD` =  1

But after execution there also changes ci_users.user_creation_date field. Where there may be a problem? 

A:

That's what timestamp fields are for.
If you don't want them to be altered on update - use DATETIME instead
