Syntax Error SQL Codeigniter - sql

Question

I have this in my code and im using codeigniter yet it's producing an error
// make call to db and create a file
$this->db->select("*");
$this->db->from("mst_global_settings mgs");
$this->db->join("trans_global_settings tgs", "mgs.global_name_id=tgs.global_name_id", "inner");
$this->db->where('`tgs`.lang_id', $lang_id);
$query = $this->db->get();
$result = $query->result_array();
$tmp_array = array();
foreach ($result as $global_array) {
$tmp_array[$global_array["name"]] = $global_array["value"];
}
Codeigniter is giving me the following error
Error Number: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'tgs`.`lang_id` = 'en'' at line 4
SELECT * FROM (`p931_mst_global_settings` mgs) INNER JOIN `p931_trans_global_settings` tgs ON `mgs`.`global_name_id`=`tgs`.`global_name_id` WHERE `p931_`tgs`.`lang_id` = 'en'

The problem is your single quotes.
Change this:
$this->db->where('`tgs`.lang_id', $lang_id);
To this:
$this->db->where('tgs.lang_id', $lang_id);
