I am trying to export the list of Like and Liked interaction by topics remixing the sample code, and realized that the topics I was particularly trying to look at seemed to not be included in the list. The code I tried was:
WITH pairs AS ( SELECT p.user_id liked, pa.user_id liker, p.topic_id topic FROM post_actions pa LEFT JOIN posts p ON p.id = pa.post_id WHERE post_action_type_id = 2 --2 means liked ) SELECT liker liker_user_id, liked liked_user_id, topic topic_id, count(*) FROM pairs GROUP BY liked, liker, topic_id ORDER BY topic_id DESC
I’ve noticed that the difference between the topics I am looking for and the topics I get is that the former’s topic_id is nested: example one and two. These topics with nested topic_id were created last year, reorganized as a new category early this year, because we needed to create topics with the same titles to run the same set of discussion with a new group of people.
Please let me know if anyone know how I should find those, or any ideas to retrieve data from those topics with nested topic_id.
I really appreciate your help in advance!
