Решено! Проблема с большим SQL запросом

Здравствуйте, уважаемые форумчане.

Я делаю парсер для Joomla и запись в БД решил сделать одним большим SQL запросом (из соображений производительности), но $db->query() возвращает false и в БД ничего не записывается, хотя если этот же запрос выполнить в PHPMyAdmin, то он выполняется без ошибок и записи добавляются нормально. Joomla ни на странице, ни в логах никаких ошибок не выводит (естественно в конфигах сервера отображение ошибок включено на максимум).

Может быть кто-то уже работал ранее с длинными запросами в БД и сможет подсказать куда копать? Да и вообще как можно выяснить причину ошибки? Гуглил несколько статей по отладке запросов в БД Joomlы, но так и не смог ничего вывести.

Запрос делаю конечно же через фрэймворк Joomlы.
