Когда я проверить это с помощью почтальона он выдает следующее исключение:
An unhandled exception of type 'System.StackOverflowException' occurred in EntityFramework.dll
Я искал об этом, но мое дело обстоит иначе, если я пропустить выберите VALES мой запрос работает нормально. Я не знаю почему. но без пропусков это исключает исключение.
Пожалуйста, помогите ..
Извините за это, но этот запрос безумный. Вы должны нормализовать свою модель данных, прежде чем пытаться сделать этот шаг дальше. Впоследствии создайте различные части пользовательского интерфейса на отдельных этапах. Зачем все это в одном недостижимом монолите? –
Кроме того, 'StackOverflowException' трудно обнаружить, не имея возможности запускать код (и даже тогда). Но я уверен, что LINQ-to-SQL задыхается в количестве кода SQL, который он пытается сгенерировать. –
@Gert Arnold Что делать, если это требования от клиента. Я знаю, что это безумие, но как я могу это сделать. – user3253756
