array $options: An associative array of options to control how the query is run.

Return value

\Drupal\Core\Database\StatementInterface|int|null Most database drivers will return NULL when a PDO exception is thrown for a query, but some of them may need to re-run the query, so they can also return a \Drupal\Core\Database\StatementInterface object or an integer.
