Я сталкиваюсь с этой неоднозначно определенной ошибкой.Я понимаю, что это связано с неправильным определением псевдонима, но я не могу понять в следующем запросе, почему возникает эта ошибка.Я использую Oracle.

Я определяю таблицу paam
и таблицу papf
одинаково и не сталкиваюсь с проблемой в них.
Почему я сталкиваюсь с этой ошибкой при попытке добавитьfabu
таблица в конце?
