How to recreate full SQL query in Qt 6 (removed feature?!!!!)

QString DatabaseFactory::lastExecutedQuery(const QSqlQuery& query) {
  QString str = query.lastQuery();
  QMapIterator<QString, QVariant> it(query.boundValues());

  while (it.hasNext()) {
    it.next();

    if (it.value().type() == QVariant::Type::Char ||
        it.value().type() == QVariant::Type::String) {
      str.replace(it.key(), QSL("'%1'").arg(it.value().toString()));
    }
    else {
      str.replace(it.key(), it.value().toString());
    }
  }

  return str;
}
