No tables used

I need your help
I want to update a database, but I get an error message 
Error Number: 1096
No tables used

SELECT * WHERE 0 = 'Small' LIMIT 1

Filename: C:/xampp/htdocs/billing/system/database/DB_driver.php
Line Number: 691

and this is the query syntax in the model
public function edit($data)
   {
      $this->db->where('id_type', $data['id_type']);
      $this->db->update('type', $data);
   }

but in different models using such a syntax does not get an error message
