interface StatementInterface

Represents a prepared statement.

Child implementations should either extend PDOStatement:

class Drupal\Core\Database\Driver\oracle\Statement extends PDOStatement implements Drupal\Core\Database\StatementInterface {}

or define their own class. If defining their own class, they will also have to implement either the Iterator or IteratorAggregate interface before Drupal\Core\Database\StatementInterface:

class Drupal\Core\Database\Driver\oracle\Statement implements Iterator, Drupal\Core\Database\StatementInterface {}
