Get updates from current user and all their friends - mysql query

Question

I'm building a Facebook-like wall and wish to retrieve all updates from both the current user and all their friends.

As it stands I'm only getting updates from user's friends. How do I include user's own updates too?

SELECT  M.msg_id, 
    M.uid_fk, 
    M.message, 
    M.created,
    U.fname, 
    U.lname, 
    M.uploads 
FROM messages M INNER JOIN  users_friends F ON F.friendID = M.uid_fk

AND F.userID = " . $_SESSION['user_id'] . "
AND F.status = 2 
            INNER JOIN users U ON U.userID = F.friendID 

            order by M.msg_id desc limit 10

Answer 1

SELECT <columns>
FROM (
    SELECT <columns>
    FROM <friends criteria>
    UNION
    SELECT <columns>
    FROM <current user criteria>
) x
order by msg_id desc
limit 10
