Запрос C # LINQ, приводящий к ошибке DB2. Типы данных выражений результата выражения CASE или функции DECODE несовместимы.

У меня есть запрос, его нужно выбрать из БД DB2, но записи должны быть сгруппированы по одному столбцу (PeopleID), чтобы приложения могли быть помещены в список для возврата требуемого объекта данных.Хотя я вижу несколько областей, в которых создаются операторы CASE, я не вижу никаких возвращаемых различных значений.

Я прошел результирующий запрос, отправленный в DB2, он генерирует ту же ошибку, но я не могу найти ничего очевидногов этом тоже.Я бы опубликовал полученный запрос здесь, но он превышает ограничение на число символов.

Я прочесывал этот код и полученный запрос DB2 в течение последних двух дней и не могу найти источник несоответствия типов данных.

В объединениях, которые мне действительно нужно привести в значение Nullable, не допускающие значения Nullable, я не вижу никакой причины, которая могла бы создать конфликт.

Я разделил два запроса linq, и он, кажется, работает нормально ... 

IEnumerable<PersonRegistrationInformationTableInformation> results = (from data in (from participant_app in DBContext.PARTICIPANT_APPLICATION
                                                                        join people_vendor in DBContext.PEOPLE_VENDORS on participant_app.PEOPLE_ID equals people_vendor.PEOPLE_VENDORS_ID into tmppeople_vendor
