Доброго времени суток господа, возник такой вопрос, даже не знаю правильно ли я здесь тему создал или надо было в ветке запросов к бд, в общем суть такова в таблице product есть нужные мне поля - url, download, type я сделал еще один запрос, это в принципе работает, но правильно то было бы добавить это в основной запрос, но я не могу понять как это сделать, подскажите если не сложно, или наоборот так правильно как я сделал отдельным запросом?
