Это работает достаточно хорошо (помимо скорости).Я хочу создать таблицу, которая в основном является хранилищем данных этих предыдущих записей, чтобы я мог быстрее извлекать их и обновлять хранилище по мере необходимости.
Однако, поставив CREATE TABLE records_warehouse перед моим запросом, теперь я получаю Error Code: 1060: Duplicate column name 'type'.Я вижу только один столбец с именем type, и также нет проблем, когда я просто выполняю только оператор SELECT.Почему это происходит и как я могу обойти это?
