Answer 1

通常你会这样做一个JOIN：

SELECT rt.room_name AS Room, at.amenities_name AS Amenities FROM
link_table AS lt JOIN room_table AS rt ON lt.room_id = rt.room_id
JOIN amenities_table AS at ON lt.amenities_id = at.amenities_id;

得到这样的结果：

Room       Amenities
--------------------
Room 101   WIFI
Room 101   A/C
...        ...
Room 102   A/C
...        ...
