Answer 1

You can use alias of the table and then select those
NOTE : I highly recommend you to use * if and only if your using all the columns else it will make your query bit slower.
/* You can take an alias for the table and select * from that, I have followed chaining method. */
$this->db
->select('v.*, s.*')
->from('tbl_village v')
->join('tbl_school s', 's.school_id = v.school_id', 'left')
->get()
->result_array();

You can try this solution for your problem :
Please change your modal function :
all_village_info:
public function all_village_info($id = NULL) {
$this->db->select('tbl_village.*', FALSE);
$this->db->select('GROUP_CONCAT(tbl_school.school_name ORDER BY tbl_school.school_id) as school_name', FALSE);
$this->db->from('tbl_village');
$this->db->join('tbl_school', 'FIND_IN_SET(tbl_school.school_id, tbl_village.school_id) > 0', 'left');
if (!empty($id)) {
$this->db->where('tbl_village.village_id', $id);
$query_result = $this->db->get();
$result = $query_result->row();
} else {
$query_result = $this->db->get();
$result = $query_result->result();
}
return $result;
}
I hope it will help you.
