Question

I’m trying to get app users in javascript sdk.
Why this is not working?

var q = FB.Data.query('SELECT uid FROM user WHERE uid IN '
            + '(SELECT uid2 FROM friend WHERE uid1 = me()) AND is_app_user = 1');

q.wait(function(resp) {
        console.log(resp);
    }
);

That returns []

However that works well:

var q = FB.Data.query('SELECT uid2 FROM friend WHERE uid1 = me()');
q.wait(function(resp) {
        var l = [];
        for (var i in resp) {
            l.push(resp[i].uid2)
        }
        var fql = 'SELECT uid FROM user WHERE uid IN (' + l.join(',') + ') and is_app_user = 1';
        var q1 = FB.Data.query(fql);
        q1.wait(function(resp) {
            console.log(resp);
        });
    }
);

The problem with the second statement is that loads all friends into browser and it makes one more request. Why isn’t the first statement working?

Answer 1

try treating is_app_user as a boolean:
(works for me using just fql)

var q = FB.Data.query(‘SELECT uid FROM user WHERE uid IN ‘
+ ‘(SELECT uid2 FROM friend WHERE uid1 = me()) AND is_app_user’);
