Try this

   $this->db->select('*')
            ->from('student')
            ->where('student.roll_no',$id)
            ->join('student_details','student_details.roll_no = student.roll_no')
            ->join('course_details','course_details.roll_no = student.roll_no');
   $query = $this->db->get();
   return $query->row_array();
