MySQL 语句根据另一个表从一个表中获取数据

Question

I have these two tables

I need a MySQL statement that if a spot has 2 or more rows in the facility table. Lets say that I need to find spots that has both shower and toilet.

I have tried with something like this

select * 
from spot 
where spot.id IN (
                    select spot_id 
                    from facility 
                    where facility LIKE 'shower' 
                    AND facility LIKE 'toilet'
                )

But the subselect doesn't return anything while title can't be both 'shower' AND 'toilet'.

Edit: I got this working

select * from spot where spot.id IN ( select spot_id from facility where facility LIKE 'toilet' ) AND spot.id IN ( select spot_id from facility where facility LIKE 'shower' )

Answer 1

You have to use OR instead of AND or you can use IN or we can use Join as well.

select * from spot where spot.id IN (
     select spot_id from facility where facility IN ('shower','toilet'));

or

select * from spot where spot.id IN (
     select spot_id from facility where facility LIKE 'shower'
    OR facility LIKE 'toilet');

or

select s.id, s.title from spot s join facility f on s.id = f.spot_id where f.facility in ('shower','toilet');
