How to display data from the database (MySQl) in telegrambot (PyTelegramBotApi) to the inline keyboard?

Question

MySQL

The logic of the project is:
1) Sending the location to the bot
2) Displaying in the inline keyboard the names of the points closest in coordinates (10m = 0.01km)


Tell me how to proceed:

    geo_btn = types.KeyboardButton(text='Местоположение', request_location=True)
    geo.add(geo_btn)

    msg = bot.send_message(message.chat.id, "Отправте текущее местоположение:", reply_markup=geo)
    bot.register_next_step_handler(msg, process_geo_step)

    km = 6367 * c
