I see that I can access a friend's groups via the Graph API:
https://graph.facebook.com/11111111/groups
... but how do I access it via FQL? (I am searching the documentation extensively before asking these questions, sorry if I'm asking an obvious one).
if you want to get the groups of user with the id 1111111
you can write this query:
don't forget you need to have the friends_groups permission in order to get this data
the documentation for those tables can be found here:
