Disctinct

Question

ICriteria crit = session.CreateCriteria<HCOSpendTable>(); 

foreach (ICriteriaItem<object> param in filters) 
{ 
    crit.Add(Expression.Eq(param.PropertyName, param.FilterValue)); 
} 

crit.SetProjection(Projections.Distinct(Projections.ProjectionList())); 

Disctinct不工作，你可以請幫我

crit.AddOrder(new Order(sortField, sortOrderAscending)); 
crit.SetFirstResult(pageNumber * pageSize); 
crit.SetMaxResults(pageSize); 

transaction.Commit(); 

return crit.List<IHCOSpendTable>(); 

Answer 1

的ICriteria標準= session.CreateCriteria（typeof運算（人））; （Projections.Alias（Projections.Property（「LastName」））.ProProjection（Projections.Distinct（Projections.ProjectionList（）.Add（Projections.Alias（Projections.Property（「FirstName」），「FirstName」））.Add 「姓」））））;

criteria.SetResultTransformer（新NHibernate.Transform.AliasToBeanResultTransformer（typeof運算（人）））;

IList people = criteria.List（）;

Answer 2

您需要將屬性映射添加到ProjectionList()

crit.SetProjection(Projections.Distinct(Projections.ProjectionList() 
    .Add(Projections.Property("id"), "id") 
    .Add(Projections.Property("name"), "name") 
));
