IllegalStateException при группировке по годуWeek или неделя

Question

У меня есть QueryDSL JPAQuery, который должен группироваться по календарной неделе. Я получаю исключение при вызове списка (...) на нем. Пока я заменяю все вхождения yearWeek() по году(), он отлично работает.

код Java:

QCrmContact qCrmContact = QCrmContact.crmContact; 
BooleanExpression whereClause = qCrmContact.beUserId.eq(beUserId).and(qCrmContact.crmContactTypeId.in(contactTypeIds)); 

JPAQuery query = new JPAQuery(entityManager); 

query.from(qCrmContact).where(whereClause).orderBy(qCrmContact.createdDatetime.yearWeek().asc()) 
    .groupBy(qCrmContact.createdDatetime.yearWeek(), qCrmContact.crmContactTypeId); 
List<Tuple> rows = query.list(qCrmContact.createdDatetime.yearWeek(), qCrmContact.crmContactTypeId, qCrmContact.companyId.countDistinct()); 

Исключение:

Exception occurred during processing request: No data type for node: org.hibernate.hql.internal.ast.tree.MethodNode 
+-[METHOD_CALL] MethodNode: '(' 
| +-[METHOD_NAME] IdentNode: 'yearweek' {originalText=yearweek}

Было бы хорошо для меня, чтобы использовать некоторые хак и передать родной SQL в Oracle:

to_char(CREATED_DATETIME, 'IW.YYYY') 

Answer 1

Разрешен путем замены

qCrmContact.createdDatetime.yearWeek() 

с

StringExpression createdWeekYear = StringTemplate.create("to_char(CREATED_DATETIME, 'IW.YYYY')");
