Я озадачен запросом.
Мне нужно найти строку LAST, добавленную в таблицу со столбцом с типом данных. Столбец уникального идентификатора: aspnet_Applications.ApplicationId. Примечания..
Мне нужно также взять последнюю вставленную строку и обновить ее в другой таблице aspnet_Users.ApplicationId
Я пытался использовать SCOPE_IDENTITY в MS SQL 2008, но не работает, потому что SCOPE_IDENTITY работает только сИДЕНТИЧНАЯ колонка.
Вот мой код.Есть идеи?
