     * SQLSRV driver implements [[PDO::lastInsertId()]] method but with a single peculiarity:
     * when `$sequence` value is a null or an empty string it returns an empty string.
     * But when parameter is not specified it works as expected and returns actual
     * last inserted ID (like the other PDO drivers).

The expression return ! $sequence ? parent::lastInsertId() : parent::lastInsertId($sequence) returns the type string which is incompatible with the documented return type integer.
