Oracle, как архивировать справочную секционированную таблицу

Question

Я пытаюсь переместить данные из родительской таблицы, разделенной на несколько интервалов, и дочерней таблицы, разделенной по ссылке, в соответствующую структуру архивной таблицы.

И, к моему удивлению, эта, казалось бы, простая задача мне недоступна...

Я читал о перемещении секционированной таблицы в архив , но он не говорит о том, как перемещать таблицы с помощью клавиш foregin.

Я также читал о перемещенииссылаться на секционированные таблицы , но это решение не работает для меня, выдавая эту ошибку после первого оператора:

ORA-02266: уникальные / первичные ключи в таблице, на которые ссылаются включенные внешние ключи

Итак, я попробовал свой собственный подход.Это дает мне еще худшую ошибку:

ORA-00600: внутренний код ошибки, аргументы: [kkpamRefGet: index], [], [], [], [], [], [],[], [], [], [], []

Вы можете воспроизвести мою последнюю попытку так:

В настоящее время у меня нет идей, как следуетЯ делаю это, и я начинаю задаваться вопросом, стоит ли мне даже пытаться переместить эту структуру в архив ... Она разбита по датам, так что я могу просто позволить ей расти?

Буду признателен за любую помощь в этомдело.:)

ОБНОВЛЕНИЕ:

Так же, как предложено Франциско , опция CASCADE помогла с моим примером кода.Ниже приведен пример кода в рабочем состоянии.

Но в моем сценарии из реальной жизни существует более одного дочернего элемента в родительской таблице.И вот, когда я пытаюсь использовать опцию CASCADe, я получаю ORA-14706 .Предложенное решение не заключается в использовании опции CASCADE ...

Так что я до сих пор не могу заархивировать свои таблицы, и мне все еще действительно нужна помощь.
