Question

I’m trying to develop this code:

$users = $facebook->api(array(
  'method' => 'fql.query',
  'query' =>    "SELECT uid, last_name, pic_big"
             + " FROM user WHERE uid IN ("
             + "     SELECT uid" 
             + "     FROM page_fan"
             + "     WHERE page_id='411133928921438'" 
             + "         AND uid IN ("
             + "             SELECT uid2 FROM friend WHERE uid1 = me()"
             + "         )"
             + ")"
));

The idea is that i don’t want to use the operator IN but NOT IN, but FQL doesn’t support operators like NOT IN, EXCEPT… How can i do it with FQL?…

Answer 1

There is no NOT IN operator in FQL. You could do a simple select using IN and use PHP for negation. It’s a little overhead, but as far as I know it’s the only way.
