How can I use concatenation in where clause [Codeigniter]

Question

Hello I'm trying to use concatenation in where clause in codeigniter Equivelent to this in mysql

SELECT * FROM `tblstaff` WHERE concat_ws(' ',firsname,lastname) like '%Firstname lastname%'

I tried doing this in codeigniter , but didn't work

$admin = 'Firstname lastname';

$CI =& get_instance();
$CI->db->where('firstname'.' '.'lastname',$admin);

return $CI->db->get('tblstaff')->row()->default_language;

Any ideas

Answer 1

Not tested but try to change

$CI->db->where('firstname'.' '.'lastname',$admin);

to

 $CI->db->where("CONCAT_WS(' ',firsname,lastname) LIKE '%".$admin."%'", NULL, FALSE);

Answer 2

Try codeigniter's query builder $this->db->like As below:

$admin = 'Firstname lastname';

$CI->db->like("CONCAT_WS(' ',firsname,lastname)",$admin,"both");
