Answer 1

this might work:

UPDATE room_availability 
SET ${Room_type}_room = #{kamarBaru},room_date = #{booking_date}
FROM room_availability
INNER JOIN list_hotel ON list_hotel.hotel_id = room_availability.hotel_id
INNER JOIN room_price ON room_availability.hotel_id = room_price.hotel_id 
WHERE list_hotel.nama_hotel = #{hotel_name};
