Question

I am trying to build a sql query that I think it involves inner joins, but I can’t figure it out. Here’s the model:

There’s two tables: comments, posts

Among many columns, there’s the following important ones: comments.id, comments.user_id (owner), comments.post_id (reference to posts table), posts.id, posts.editor_id (which is the person, ie, owner of post).

I want to get the comments that either

1) current user has written, so something like:

select * from comments where user_id = <<current_user_id>>

2) (Assume current_user is editor). Get all comments that belong to a post that you have created.
This is what I have, but I get multiple lines….what am I missing?

select * FROM comments INNER JOIN posts ON comments.post_id = <<test_id>>
WHERE posts.editor_id = <<current_user.editor_id>>;

If you could give me a sql query that includes both of these things, that would be amazing.

Thanks!

Answer 1

Im not sure what you mean by “multiple lines” as you would return a row for each comment.
This should do it.

SELECT comments.* 
FROM comments 
INNER JOIN posts 
ON comments.post_id = posts.id   
WHERE posts.editor_id = @editorID;
