I don't particularly fancy the idea of getting a list of friends with 'me/friends' and then iterating over the list to get likes for a particular friend with '%id%/likes' - this takes way to long.
Is there a way to bulk query likes of users' friends in a single API call?
Thanks.
You can use FQL multi-query to get all at once, here is how:
{
"friends":"SELECT name, uid FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me())",
"friendsLikes":"SELECT uid, page_id FROM page_fan WHERE uid IN (SELECT uid FROM #friends)",
"pages":"SELECT page_id, name FROM page WHERE page_id IN (SELECT page_id FROM #friendsLikes)"
}
You can test this in http://developers.facebook.com/tools/explorer/
You are going to get three result sets one after another, list of friends, list of all of their likes together and then list of page names.
(Note that the query may take a while to execute, so you may want to put a LIMIT on the first line. After uid1 = me() put a LIMIT 5 for example, for testing...)
Then include it in your code in whatever language/platform you are using, for example on iOS:
http://developers.facebook.com/docs/howtos/run-fql-queries-ios-sdk/
You can also do the same query using the Graph API:
https://graph.facebook.com/me/friends?fields=name,id,likes.limit(100).fields(id,name)&limit=100
This will solve the issue of the grouping.

Facebook FQL query returns no results for languages field if there is a clause specifying languages id or name. If there is no WHERE clause for languages then all fields are returned.
SELECT uid,name,languages.name FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me()) AND (strpos(lower(languages.name), lower("English")) >= 0)
See the following link for an example:
https://developers.facebook.com/tools/explorer?fql=SELECT%20uid%2Cname%2Clanguages.name%20FROM%20user%20WHERE%20uid%20IN%20(SELECT%20uid2%20FROM%20friend%20WHERE%20uid1%20%3D%20me())%20AND%20(strpos(lower(languages.name)%2C%20lower(%22English%22))%20%3E%3D%200)%20
I have had no problems with other fields or FQL queries. All permissions are requested for authorization token.
Apparently you can't "filter" on fields containing array, filtering on fields containing objects works as you sketched out. I don't think this is documented in the Facbook API docs.
See my answer here as well: FQL Query for facebook
There is a certain event that I want to filter by gender with an fql query. This is what I have tried so far
SELECT name, sex FROM friend WHERE sex IN
(SELECT uid2 FROM eid WHERE uid1 = me()) AND sex = "male" LIMIT 10
Any suggestions?
it doesn't do the right thing I want this query to do,
I would like to filter invited members of an event by their gender.
As of v2.0 API querying by gender depends on the users currently using the application. If the user isn't using the application, you will not be able to query the gender.
I am trying to filter my friends based on work history by using fql, but fql does not return any results.
Here is the fql i am trying:
select uid,username,work from user where uid in (select uid1 from friend where uid2 = $myid) and work.employer.id IN ($someid)
i get the result -
{
"data": [
]
}
Am i doing something wrong?
This is because the work field doesn't obey like the other fields due to how the arrays are set up for each each work object. For example strlen(work.employer.id) gives 0.
So in short FQL doesn't support this feature. You can try submitting a bug report.

Fetching list of friends in Graph API or FQL - Appears to be missing some friends

Closed 9 years ago.
I am working on FQL to retrieve the friends count of a particular user.
When i use the query Select friend_count from user where uid = me() I get a number which is different from the count i get from this query i.e select uid2 from friend where uid1= me()
Why is an ambiguity here?
Does friend_count also includes pending requests then?
If yes how can retrieve those UIDs?
Select friend_count from user where uid = me() returned me X and select uid2 from friend where uid1= me() returned me Y.
My X is greater than Y which makes me think if X includes the pendin g requests but i am not able to find (X-Y).
The difference is that friend_count returns the total number of friends, regardless of their privacy settings.
Counting the results of SELECT uid2 FROM friend WHERE uid1= me() may be lower because users who have either restricted their visibility in Settings->Apps->Apps Others Use or have turned off Platform Apps will never be returned in FQL or Graph API queries.
I'm just getting started with developing with using facebook api with php.
But I can't seem to figure out why I get only an empty array when I invoke the following query:
$fql = "SELECT message,time FROM status WHERE uid ='".$uid."'";
$response = $facebook->api(array('method' => 'fql.query','query' =>$fql));
print_r($response);
When I use a different query like the following I'm getting result back:
$fql = "SELECT uid2 FROM friend WHERE uid1='".$uid."'";
There may be an issue with permissions. You may need to grant user_status permission.
See here - http://developers.facebook.com/docs/authentication/permissions
Check your permissions. A great way to do this is to use the FQL Query Tool. Its great to test queries and the permissions you will need to access the data you are querying
I have the similar problem, just instead I use:
{
"id":"SELECT uid1, uid2 FROM friend WHERE uid1 = me()",
"posts":"SELECT message, time FROM status WHERE uid IN (SELECT uid2 FROM #id) ORDER BY time DESC LIMIT 50"
}
As a result I get:
{
"name": "posts",
"fql_result_set": [
]
}
If I change uid2 to uid1: (SELECT uid1 FROM #id)
I get my status updates.
2 weeks ago, this was working.
Permissions, in my case are correct.
Note: Query's are in Graph Explorer format, so they can be easyly tested
