Facebook FQL. Table 'columns' contain wrong fields - facebook

Why the next Facebook FQL:
select column_name from columns where table_name = 'user' order by column_name
return are different list of columns then in api page http://developers.facebook.com/docs/reference/fql/user
for example it return field 'can_viewer_send_poke_message' but facebook tell that
(#602) can_viewer_send_poke_message is not a member of the user table
So, I just trying to automate process to keep some hql queries with full list of Columns of each hql table.
May be is there some other way to get for each table column list as string separated with ","?

This is a private field for Facebook Developers of the Official Poke Application for iPhone. It checks whether the users listed (friends) can use the poke application.

Search facebook group using the name as a search term on Facebook FQL

I've tried using the Facebook Graph API. But the results came out, it did not show up to 150 groups. I'm not sure that it is a limitation of Facebook or not.
An example URL that I tested.
Now, I would like to test the FQL Query. But did not succeed. I have the following error
(#604) Your statement is not indexable. The WHERE clause must contain an indexable column. Such columns are marked with * in the tables linked from http://developers.facebook.com/docs/reference/fql
This is a SQL statement
SELECT gid, name, privacy FROM group WHERE strpos(name, "programming") >= 0

Use Facebook API to list group members' join date and inviter

I can use the Facebook Graph API to get a list of group members. The simplest way to do this is to go to the Graph API Explorer and do a GET request of the form {group_id}/members. Is there a way to similarly obtain the members' join date and who they were invited by?
The relevant Graph API doc doesn't seem to mention it. But I know the information is stored by Facebook because it is possible to list all of the group members and their inviters through Facebook itself. Is there a way to get this information through the API?
EDIT: Nothing in the FQL group or group_member API either.
While this information is not available on the API, you can get it by using Selenium to scrape the members page.
First, instantiate a driver and use it to get the members page:
driver.gethttps://www.facebook.com/groups/your group number/members
Then, look for the member information:
containers = driver.find_elements_by_tag_name('td')
Finally, iterate through the web elements, extracting text and parsing resulting list for joined date information:
member_info = container.text.split('\n')
name = member_info[0]
member_since = member_info[-1]
You'll still have to map this information to the user ids, which you can do by looking for another element in the container and using REGEX.
`def parse_id(self, container, name):
hovercard = container.find_element_by_link_text(name).get_attribute('data-hovercard')
regex_id = re.compile('php\?id=(\d*)')
member_id = regex_id.search(hovercard).group(1)
return member_id`
It is indeed stored by Facebook and retrieved for use with internal APIs. For the Graph API however it is not possible to get this information.
All the fields available for a group_member are listed at SELECT column_name FROM column WHERE table_name = "group_member"

Joining two tables and fetching records in a single query in FQL

Hi i have written a query by which i can fetch posts,actor_id,comments and other columns required from stream table. But i want to fetch user's name also along with actor id and other columns in a single query.
My queries is :
select message,created_time,actor_id,attachment,comments,created_time,impressions,likes,message,message_tags,place,share_count from stream where source_id in (any_page_id)
I want to add user's name also from user table along with this list of columns i am fetching from stream table in a single query so that i can handle it in a single json file. .
Also in comments we will get several user's id with comments as from_id. Can we get username for this from_id also. Is this possible, i know we cannot use join in FQL. Or i am missing something or in a wrong approach. Please help me out. Thanks in advance.
Updated
Now i am able to get actor_id and other fields of the post together along with user's name at the end in the same json using multi-query. Something similar to :
fql?q={"query1":"select+message,created_time,actor_id,attachment,comments,created_time,impressions,likes,message,message_tags,place,share_count+from+stream+where+source_id+in(any_page_id)","query2":"select uid,name from user where uid in (*#query1* "}
But now i am not able to get the user's name and user's id who are there in the comments of the post in the same json.

FQL search public posts

I'm trying to do a search using FQL.
Using the Graph API, it works but there are more options using FQL.
Using something like
https://graph.facebook.com/search?q=myquery&access_token=mytoken
it work fine.
I'm looking for the equivalent in FQL.
What query I must write in here
https://api.facebook.com/method/fql.query?query=SELECT%20post_id%2C%20actor_id%2C%20target_id%2C%20message%20FROM%20stream&access_token=mytoken
The query above give me that
Parser error: unexpected end of query
I want to search in all public posts.
I've been looking everywhere but I did not found any solution.
Thanks.
For searching public posts for a string, you need to use the Graph API, and then filter those posts in your script. I don't think searching all public posts is possible in FQL. While FQL is more powerful, it is also more limited.
You are getting an error because you don't have a "WHERE" clause in your query. This is required in FQL.
The limit comes in because you must use at least one indexed column in your WHERE query. For the stream table you must specify either a post via post_id, a user via source_id or filter_key, or a live stream via xid. The indexed fields are marked with a * on the documentation site.
For instance, [this FQL][1]
SELECT post_id,actor_id,target_id,message FROM stream WHERE filter_key = 'others'
AND strpos(message, 'the') >= 0
will get you all posts that show on your access token owner's wall that have not been posted by the owner, with the string 'the' in them. That is the best you can get. If the post isn't visible on their wall, then you won't get the post.
If you try to leave out an indexed field, FQL will throw a 'Your statement is not indexable' error.
[1]: SELECT post_id,actor_id,target_id,message FROM stream WHERE filter_key = 'others' and strpos(message,'the') >=0

How to retrieve page ids based on type using FQL?

I want to retrieve page ids of all those pages whose type is Musician/Band. I tried to retrive it from page table as
SELECT page_id from page where type='MUSICIAN/BAND'
but it is not allowing that.Its giving error:
Your statement is not indexable. The WHERE clause must contain an indexable column.
How to go about this?
You simply cannot do that query. You need to include at least one of the indexable columns in your query (page_id or name).
