codeigniter update issue You have an error in your SQL syntax - codeigniter

Question

I am getting the error when I am updating
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 '0 = Array WHERE order_id = '11'' at line 1
UPDATE rel_orders_prices SET 0 = Array WHERE order_id = '11'
Filename: modules/admin/models/Booking_model.php
Line Number: 241

Answer 1

You should use backticks for the column name, because it contains only numbers and the value should be within quotes, so this should work:
UPDATE rel_orders_prices SET `0` = 'Array' WHERE order_id = '11'
Identifiers may begin with a digit but unless quoted may not consist solely of digits.

Answer 2

try this query in your model file.
function update($order_id,$insertArray){
return $this->db->where('order_id', $order_id)->update('tablename',$insertArray);
}

Answer 3

Use this like,
$this->db->set('save_price',$save_price);
Because column name missing.
If array then,
$this->db->set(array('save_price'=>$save_price));
OR
$this->db->update('rel_orders_prices',array('save_price'=>$save_price));
