Codeigniter : Error in ORDER BY CASE query

Question

Here is my query in Codeigniter

$this->db->select(\'p.*,u.firstname, u.lastname,s.title AS industry, pt.type_name , al.length_value\',         


        

Answer 1

I figured it out how to avoid escaping CASE word.

You can modify $_reserved_identifiers variable inside CI_DB_driver class. If you don't want to modify whole file, you can simply change it inside your Model class just before that query.

$this->db->_reserved_identifiers = array('*','CASE');

$this->db->select('p.*,u.firstname, u.lastname,s.title AS industry, pt.type_name , al.length_value',FALSE);
$this->db->from($this->_tbl_projects . ' as p');
$this->db->join($this->_tbl_client_details . ' as c', 'c.id = p.client_id', 'left');
$this->db->join($this->_tbl_users . ' as u', 'u.id = c.user_id', 'left');
$this->db->join($this->_tbl_project_types . ' as pt', 'pt.project_type_id = p.project_type_id', 'left');
$this->db->join($this->_tbl_specializations . ' as s', 's.specialization_id = p.specialization_id', 'left');
$this->db->join($this->_tbl_article_length . ' as al', 'al.article_length_id = p.article_length_id', 'left');
$this->db->order_by("CASE p.submit_to
                                WHEN '' THEN 0
                                WHEN 'writer' THEN 1
                                ELSE 2
                            END, p.request_end_date asc",FALSE);

(I don't know if it's working on 3.x branch. It's working good on 2.x branch)
