For eg:If there are 5 id, but when I search the id to get the name from another db it shows the 1st id name only.What's the problem I don't know pls help me.

You could get it done (getting names list) by directly using join() method like this :
public function fetch_emp()
{
$this->db->select('emp_name');
$this->db->from('emp');
$this->db->join('employee_master', 'employee_master.emp_id = emp.emp_id');
$res=$this->db->get();
return $res->result();
}
