Как вызвать id каждого пользователя aiogram, sqlite?

Question

[kkqqff]

Как дополнить данный handler? Не знаю как вызвать id каждого пользователя по очереди для рассылки всем авторизованным пользователям из базы данных sqlite. Все функции из бд и код handeler'a привел. Pycharm пишет: UNIQUE constraint failed: Users.id

@dp.message_handler(user_id=admin_id, commands=['tellall'])
    async def mailing(message: types.Message):
        await message.answer(text="Пришлите текст рассылки")
        await Mailing.Text.set()

    @dp.callback_query_handler(user_id=admin_id, state=Mailing.Text)
    async def mailing_start(call: types.CallbackQuery, state: FSMContext):
        text = message.text
        await state.update_data(text=text)
        await state.reset_state()
        users = db.select_all_users()
        for user in users:
            try:
                await bot.send_message(chat_id=db.select_user(),
                                       text=text)
                await sleep(0.3)
            except Exception:
                pass
        await call.message.answer("Рассылка выполнена.")
