возможно дубликат [MySQL ошибки 1022 при создании таблицы] (http://stackoverflow.com/questions/15014592/mysql-error-1022-when-creating-table) –

Ошибка 1022 указывает на то, что есть дубликат ключ –

Вы повторно используете существующие имена ограничений (id_administrador уже используется в качестве имени ограничения в таблице cadastro_usuario, а CNPJ используется в примере таблицы), вам придется указывать свои ограничения на уникальные имена (здесь я переименовал их в cf_id_administrador/CF_CNPJ);
