Sql server 引用的表中没有主键或候选键'；酒店'；与外键'；fk#U客房酒店'；

你好，有人能帮我解决这个错误吗。我只是在学习SQL，不知道如何修复它。 它表示引用的表“hotel”中没有与外键“fk_rooms_hotel”中的引用列列表匹配的主键或候选键

hotel的主键当前为（hotel\u id，addresses\u address\u id），因此您不能仅在（hotel\u id）上的外键中引用它。您可能需要将hotel的主键更改为just（hotel_id）。

该消息是解释性的。在已指定fk_rooms_hotel外键的创建表'rooms'DDL中，表'hotel'不包含列hotel_id。可能它的名称有所不同？是的。在答案中修正了它。
