Question

Have an article model, each article has an author and publisher (both are tables). A user can follow authors and publishers.

User -> Follow -> Author or Publisher -> Article

I want to find all the articles by the authors and publishers they are following.

SELECT articles.*, articles2.* FROM follows 
INNER JOIN articles ON follows.author_id = articles.author_id
INNER JOIN articles AS articles2 ON follows.publisher_id = articles2.publisher_id
WHERE follows.user_id = 1

Can I get all the articles into 1 query? If so how? If not can I combine two queries and then order them?

Answer 1

select a.* from follows f
inner join articles a on (a.author_id = f.author_id or a.publisher_id=f.publisher_id)
where f.user_id = 1
