Database SimplePdo

hi,

i have problem when using SimplePdo with method fetchField().
when the query return empty record, that method raise the error "Call to a member function getData() on null".

i think the better is have result checking before call getData(), like this :

public function fetchField(string $sql, array $params = [])
{
      $result = $this->fetchRow($sql, $params);
      if (!$result) return false; //this checking the result is not null and return false
      $data = $result->getData();
      return reset($data);
 }

thank you.
