Top Level Comments:- These are individual comments to the post itself, and not replied to any comment. This view is called "top level". The comments in this view might be ranked on the basis of their quality, replies, and some other factors.
Replies:- This view, called "replies" fetches replies to an individual comment of a post.
Comment Streams:- "stream" will return all top level comments and their replies in a chronological order, so the top level comments here won't be ranked.
FQL Commands
For Top Level CommentsThe first view of the comments on a post is called "top level". The comments that are on the post (and are not replies to individual comments) are called "top level comments." Top level comments may be ranked, depending on the post and the number of top level comments on that post so far.
SELECT id, fromid, time, text, likes
FROM comment
WHERE object_id={object_id} AND parent_id='0'
For Replies
SELECT id, fromid, time, text, likes
FROM comment
WHERE parent_id={comment_id}
For Comments Streams
Another view of the comments on a post is the "stream". The comments "stream" gives all comments (top level and replies to comments) together. The "stream" view provides comments in chronological order, so it's easy for you to just get what's new.
SELECT id, fromid, time, text, likes
FROM comment
WHERE object_id={object_id}
ORDER BY time
