MYSQL 錯誤不是唯一的表/別名 SQL 連接表與 INNER JOIN

Question

我嘗試使用 INNER join 在數據庫中更新我的表，但它一直顯示錯誤我正在使用 MYQSL 5.5這是我在映射器中的代碼

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 ${Room_type}_room = #{kamarBaru},room_date = #{booking_date}
    WHERE list_hotel.nama_hotel = #{hotel_name};

這是錯誤

    ### 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 = ?;
### Cause: java.sql.SQLSyntaxErrorException: Not unique table/alias: 'room_availability'] with root cause
java.sql.SQLSyntaxErrorException: Not unique table/alias: 'room_availability'

這是我在 SQLYog 中的數據庫設計

有人能告訴我我在這里做錯了什么嗎？

Answer 1

這可能有效：

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};
