List of gallery ids

Hello!

My brain had a bad day yesterday ^_^I found out by myself what i wanted, so i post it:

$sql = "SELECT distinct post_name FROM {$wpdb->posts} WHERE ID IN (
		SELECT distinct post_id FROM {$wpdb->postmeta} WHERE meta_key = '_cycloneslider_settings' ORDER BY post_id
		)";
	$rows = $wpdb->get_results( $sql );

	$opt = "<select id='tinymce-slider-id_select'>";
	$opt .= "<option value='none'>-- Selecciona --</option>";

	foreach ($rows as $r) {
		$opt .= "<option value='{$r->post_name}'>{$r->post_name}</option>";
	}
	$opt .= "</select>";

Just in case it helps someone ??
