与 UNION SQL 查询相反

Question

我有 2 张桌子：

interests (storing the interest ID and name)
person_interests(storing the person_id and interest_id)

如何选择特定人未选择的所有兴趣？

我已经尝试了以下 SQL 查询，但仍然没有得到想要的结果

SELECT * 
  FROM interests LEFT JOIN person_interests 
               ON interests.id=person_interests.person_id
 WHERE person_interests.id IS NULL 
   AND person_id=66;

Answer 1

用 NOT EXISTS

SELECT *
FROM interests
WHERE NOT EXISTS (
        SELECT person_interests.interest_id
        FROM person_interests
        WHERE person_id = 66
            AND interests.id = person_interests.interest_id
        )
