Answer 1

First of all you should fix your database structure. Here’s mine suggestion:

users - id (int), username (varchar)
status_updates - id (int), users_id (int), status (text)
follow - users_id, following_users_id

Please note, that you shouldn’t save users username in each table, save it only in users table. Also, username should be varchar type.

And here is your query in fixed database:

SELECT u.username, s.status
FROM users u
LEFT JOIN follow f ON u.id = f.following_users_id
LEFT JOIN status_updates s ON u.id = s.user_id
WHERE f.user_id = USER_ID
