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

here is the error

    ### Error updating database.  Cause: java.sql.SQLSyntaxErrorException: Not unique table/alias: 'room_availability'
### The error may involve Hotel.insertUpdateRoom-Inline
### The error occurred while setting parameters
### SQL: UPDATE room_availability INNER JOIN room_availability ON list_hotel.hotel_id = room_availability.hotel_id         INNER JOIN room_price ON room_availability.hotel_id = room_price.hotel_id SET deluxe_room = ?,room_date = ?         WHERE list_hotel.nama_hotel = ?;

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};
