По предложению многих я учу PDO выполнять большой запрос PHP MySQL.Что не так с моим запросом?Код представляет собой всего лишь одну отправку больших форм, и каждый рекомендует PDO вместо ручного кодирования большого запроса mysql.
Сам запрос дает жалобу от Dreamweaver, но не от Zend Studio.Что-нибудь может быть не так?
