Создать проблему с резюме

Question

Я работаю над проектом онлайн-системы управления резюме, и я сталкиваюсь с исключением при создании резюме. [b] Исключение: несоответствие типа данных в выражении критериев. [/ B]

Answer 1

ошибка указывает на проблему с одним созданных SQL-операторов. Если вы удалите блок catch, но в блоке finally, чтобы закрыть соединение, вы должны уметь видеть, какой оператор вызывает исключение. Мое лучшее предположение - проблема форматирования с одной из ваших дат.

Кроме того, вы должны действительно рассмотреть возможность использования параметризованных запросов. У этого есть SQL Injection Attack, написанная во всем этом.
