Использование результата из агрегата в неагрегате, вызывающего проблемы с GROUP BY

Question

У меня есть один столбец в моем запросе, который вызывает проблемы с моей группой. Если я включаю столбец в группу, я получаю ошибку: «Предложения GROUP BY и WITH ... BY могут не содержать агрегатных функций». но если я удалю столбец из GROUP, я получаю: «Выбранные неагрегатные значения должны быть частью связанной группы».

Я считаю, что проблема заключается в том, что, хотя столбец не агрегирует себя, он использует столбцы, которые являются агрегатными. Пожалуйста, сообщите мне, если я прав в этой проблеме и/или как я могу исправить.

Обязательно не используйте позиции столбцов для агрегации.
