Вложенный выбор с использованием HQL

Question

Я хотел бы знать, могут ли обрабатываемые производные запросы обрабатываться HQL? У меня есть этот кусок кода прямо здесь и он продолжал говорить, что он не ожидал, что символ «(» сразу после первого ОТ ключевого слова. Ваша помощь будет высоко ценится. Спасибо.

"SELECT new " + Distribution.class.getName() + " (adhoc, deployment, design, development, " + 
"enhancement, requirements, testing) FROM (" + 
    "SELECT AVG(week_adhoc) as adhoc, AVG(week_deployment) as deployment, AVG(week_design) as design," + 
    "AVG(week_development) as development, AVG(week_enhancement) as enhancement, AVG(week_requirements) as requirements," + 
    " AVG(week_testing) as testing, AVG(week_training) as training FROM " + 
     "(SELECT dist.id, sum(dist.adhoc) as week_adhoc, sum(dist.deployment) as week_deployment," + 
     "sum(dist.design) as week_design, sum(dist.development) as week_development," + 
     "sum(dist.enhancement) as week_enhancement, sum(dist.requirements) as week_requirements," + 
     "sum(dist.testing) as week_testing, sum(dist.training) as week_training from " + Distribution.class.getName() + " dist " + 
     "where dist.week=1 and dist.month=1 and dist.year=2010 group by dist.id))"; 

Answer 1

вы считаете реализовать с использованием ICriteria вместо HQL? сделать код более читаемым и программируемым.
