Im trying to query the Facebook graph api to retrieve a specific list of photos. I have photo ids stored within an object. Is it possible to insert the object within the where clause of the FQL query and if so what is the syntax?
The query is:
"SELECT object_id, images FROM photo WHERE pid =' " + photos.photoId + "ORDER BY created DESC"
photos is an object containing the user_id and the photoId.
Thanks
Since FQL queries are strings you have to convert all of the PIDs in that object to a string such that you can use the in syntax.
An example of this would be
select uid1 from friend where uid2 in (4,5)

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
I would like to know if it's possible to get, for example, all the posts that the user liked for the last 6 month.
Tell me if I'm wrong but this query is supposed to return all posts I liked :
SELECT object_id, post_id FROM like WHERE user_id = me()
I don't see how to filter the result.
You cannot grab the post_id that easily from the like table. The ONLY way to get a post_id is querying it from the stream table. This is no arbitrary query.
Here is how you should be thinking about it.
First you have to grab the posts from your stream that were posted by the "owner" since that's the easiest way to arbitrarily grab a bunch of posts that you care about.
select post_id
FROM stream
WHERE filter_key="owner"
Then you have to use that result to check if those post_ids are in your like table AND you're the user that liked them:
select post_id
FROM like WHERE
post_id in (select post_id from stream where filter_key="owner"
and created_time> *timestamp from a week ago*)
AND user_id=me()
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.
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.

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

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.
