Re: Select rows when all all ids of its children records matches

[Ron <ronljohnsonjr@xxxxxxxxx>]

Maybe this:
select p.id, p.name
from posts p,
     posts_tags pt,
     tags t
where t.id in (1, 2, 3)
  and t.id = pt.tag_id
  and pt.post_id = p.id;

I have a table posts(id, name), posts_tags(post_id, tag_id) and tags (id, name) ... I want to get all posts which has tag id 1, 2 and 3 for example. How should I do this? I tried ALL, but it didn’t work.

Those tag ids comes from UI by users, so I am looking for generic approach.

Thanks,
