Retrieving a User’s Friends

Problem

I need to retrieve all of a specific user’s friends using FQL.

Solution

This is a really simple query:

SELECT uid2 FROM friend WHERE uid1 = $uid;

Discussion

Luckily for FQL users everywhere, this query returns exactly the same result if you run it the other way around:

SELECT uid1 FROM friend WHERE uid2 = $uid;

You can run this query only when you’re looking for the friends of the current loggedinuser, or you’ll get an “Error 604: Can’t lookup all friends of 12345; only for the logged in user” error (see 600 Errors for more info).
