Актуализирайте колоната на набора от таблици, равна на това да изберете къде ID съвпада извън заявката в Oracle

Когато използвате WITH с UPDATE, трябва да използвате псевдоним за таблицата за актуализиране. Ако не, не работи.

Освен това не можете да извикате АКТУАЛИЗИРАНАТА ТАБЛИЦА в КЛАУЗАТА WITH, в този момент тази таблица е неизвестна, поради което получавате НЕВАЛИДЕН ИДЕНТИФИКАТОР. За да разрешите проблема, трябва да премахнете това условие и да го добавите в края.

Опитайте този, но пиша, без дори да знам модела на данните, така че имайте предвид.
