Use gform_after_submission to update an entry

Hi,

I'm using gform_after_submission to populate a table in database after a person submit a form:

add_action("gform_after_submission_5", "input_fields", 10, 2);
function input_fields($entry, $form){
    global $wpdb;
		$id = $entry['id'];
		$date = $entry['date_created'];
		$title = $entry['1'];
		$firstname = $entry['2.3'];
		$lasname = $entry['2.6'];
$SQL = "INSERT INTO abstracts ( abstract_id, date, firstname, lasname ) VALUES ( '$id', '$date', '$firstname',  '$lasname' )";
 $wpdb->query($SQL);
}

I also using a plugin Admin&Single Gravity Forms Add-On that simulate a post and let the users to edit their entry with a given link (/.../form/?rid=1).

When someone submit the modified form, the entries are updated in the gravity forms database, but the gform_after_submission doesn't update the other database.

I think will be the same if I edit the entry by the admin side.

How is possible to update the entry also in the second database?

Than you, Marco

I am looking to do something similar but gform_after_update_entry returns an entry_id rather than the entire entry like gform_after_submission does. Is there something to retrieve the full entry from the entry_id? I've looked through the documentation but don't see anything like that.

I used gform_after_submission to send the entry information to another system of ours. If I update that entry in WordPress I want it to update that entry information in this other system, however gform_after_update_entry doesn't supply the entry information, just the ID.
