Question

I can get pair of user_id - url from url_like table.
The only two columns are, as mentioned, user_id, url.

I tried to get get date of ‘liking’ the URL by many ways, by connecting multiple tables, but no luck.
One of many examples might be

SELECT url, id, type, site FROM object_url WHERE url IN (
    SELECT url FROM url_like WHERE user_id = {$target}
) LIMIT 1000",

Is there any way how to get date/timestamp of when user liked particular URL?

As said I even tried impossible…

I found this solution that solves my problem

I rely on FQL

public static $since = '2012/01/01';
...
...

// $target1 stands for "me", it has value of my FB ID
// So I am selecting all links I liked in past year
$object_id_raw = static::$facebook->api(array(
    'method'    => 'fql.query',
    'query' => "SELECT link_id FROM link WHERE owner = {$target1} AND created_time > ".strtotime(static::$since)
));
// Just extracting IDs for later usage
$object_id = array();
foreach($object_id_raw as $oid):
    array_push($object_id, $oid['link_id']);
endforeach;

// - friendId stands for FB ID of my friends
// This query is selecting from links I liked,that means we have them liked both...
// This API call returns object ID's (ID's of links). Do whatever you want with them...
$result = static::$facebook->api(array(
    'method'    => 'fql.query',
    'query' => "SELECT object_id FROM like WHERE object_id IN ('".implode("','", $object_id)."') AND user_id = {$friendId}"
));
