我的域名:NHibernate的:有利于构造查询
class Product
{
IList<Income> Incomes {get; set;}
Category Category {get; set;}
}
class Income
{
Product Product {get; set;}
int Quantity {get; set; }
}
我需要查询其收入的数量之和产品> 0,我能够与查询做到这一点:
ICriteria criteria = session.CreateCriteria(typeof (Income))
.SetProjection(Projections.GroupProperty("Product"))
.Add(Restrictions.Ge(Projections.Sum("Quantity"), 1));
然而,我需要根据产品属性筛选和排序查询结果的可能性 - 这就是我遇到问题的地方 - 总是得到像column "p1_.id" must appear in the GROUP BY clause or be used in an aggregate function
谢谢!我几乎要开始赏金这个问题) – kilonet 2010-09-13 18:37:29
