Database Error Occurred

Error Number: 1096

No tables used

SELECT *

Filename: C:\xampp\htdocs\speed\system\database\DB_driver.php

Line Number: 330

please help me to resolve this problem

Remove those lines:

 $query=$this->db->get();
 return $query->result();

You are inserting into the db, then you are running empty query with get()

If you want to return if the data was successfully inserted or not, then do this:

return $this->db->insert('trans_gc_add',$add);

If you want to return the inserted data:

return $add;
