I am right now using fql which brings all the friend list in array. Then I sort that array to get a random friend.
But it seems to take long time since i have to collect all the friends to get single random friend.
How do i go this in fql to get random friend?
SELECT uid, name, pic, sex FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1=me())
SELECT uid, name, pic, sex FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1=me()) order by rand() limit 1
