SQL：IN语句等效于逻辑AND

Question

我目前使用的软件中SQL对象和标签之间存在关系，如下所示：

+-----------+--------+
| object_id | tag_id |
+-----------+--------+
|       226 |     31 |
|       226 |     35 |
|       313 |     31 |
|       312 |     35 |
+-----------+--------+

使用以下请求获取具有逻辑OR的标记ID列表的所有对象ID：

select distinct object_id from tags_link where tag_id in (31, 35);

如何获取具有逻辑AND的标记ID列表的所有对象ID？

对于上表，对标记ID 31和35的请求应仅返回object_id 226.

Answer 1

select object_id
from tags_link
where tag_id in (31,35)
group by object_id
having count(distinct tag_id) = 2

Answer 2

select   object_id from tags_link where tag_id = 31
intersect
select   object_id from tags_link where tag_id = 35
