Export comments from fb:comments - comments

Question

I'm a little desperate about this. I have a site with a comments box with around 183000 comments that I want to backup. But every time I do an fql.query, I only get 100 items. I had tried:
SELECT xid, object_id, post_id, time, text, id FROM comment WHERE xid='bdatapoyo' ORDER BY time DESC
and after that, using the last "time"
SELECT xid, object_id, post_id, time, text, id FROM comment WHERE xid='bdatapoyo' AND time >= xxxxxxx ORDER BY time DESC
but the latter only gives me one comment..
I made an PHP page with this code, but again, it only grabs 100 items:
<?php
require 'php-sdk/src/facebook.php';
$facebook = new Facebook(array(
'appId' => 'XXXXXXXXXX',
'secret' => 'XXXXXXXXXX',
'cookie' => true,
));
$conexion = mysql_connect("localhost", "XXXX", "XXXX");
mysql_select_db("TVN", $conexion);
$time_old = "1315070888";
do {
$fql = "SELECT fromid,time,text FROM comment WHERE xid='bdatapoyo' AND time >= " . $time_old . " ORDER BY time";
$response = $facebook->api(array(
'method' => 'fql.query',
'query' =>$fql,
));
foreach($response as $key => $value) {
$sql = "INSERT INTO comment (text, uuid, time) VALUES ('" . $value["text"] . "', '" . $value["fromid"] . "', '" . $value["time"] . "')";
$result = mysql_query($sql);
}
$time_old = $response[count($response)-1]["time"];
print_r($time_old);
} while (count($response) > 0);
?>

Answer 1

OK, I was able to pull this out with LIMIT and OFFSET. The correct FQL is
SELECT fromid,time,text FROM comment WHERE xid='bdatapoyo' LIMIT 100 OFFSET 0
and then paging with the OFFSET

Answer 2

is this code setup to import every single comment to a db from all users on your site? What is xid=bdatapoyo?
