Я попытался выполнить следующий запрос в HQL:Выполнить запрос HQL
session1.createQuery("select p from Projet p inner join p.domaine d where p.site = :site")
.setString("site", selected)
.list();
Но в результате я получаю идентификатор таблицы Domaine, а не значение столбца, я хочу, чтобы отобразить который является строкой. PS/У меня есть много отношения между domaine и pojet. Есть я забыл добавить sometnig

Не могли бы вы добавить отображение соотношения между Domaine и ПРОЕКТУ ? – araknoid
