Get data from database of Wordpress in Plugin

I am trying to get last inserted data from WP database but it shows nothings.

My code :

global $wpdb;
    $lastid = $wpdb->insert_id;
    $table = $wpdb->prefix."videos";
    $result = $wpdb->get_results("SELECT * FROM $table WHERE id = '$lastid'");
     foreach ( $result as $print )   {

  echo '<tr>';
  echo '<td>' . $print->video.'</td>';

  echo '</tr>';

}

Please advise.
