Регистронезависимый поиск Для регистронезависимого поиска можно воспользоваться функцией UPPER: (возникает ошибка, в случае если второй аргумент больше или равен 32 Кб); • SELECT DISTINCT, ORDER BY и GROUP BY в своей работе используют BLOB ID, а не содержимое самого поля. Это одновременно и хорошо и плохо
