問題在NHibernate的

Question

創建標準，我有作爲

public class ClaimDetail 
{ 
    public virtual int Id { get; set; } 
    public virtual Claim Claim {get;set;} 
    public virtual string ServiceDateFrom { get; set; }  
    public virtual string DateCreated { get; set; } 
    public virtual ClaimDetail ParentClaimDetail { get; set; } 
} 

我想申請左外的entitiy加入對這個表作爲

SELECT cd.ClaimDetailId , 
cd.ParentClaimDetail_id , 
cds.ClaimDetailId , 
cds.ParentClaimDetail_id , 
cds.DateCreated, 
cd.DateCreated 
FROM ClaimDetail AS cd left JOIN ClaimDetail AS cds ON 
cd.ClaimDetailId = cds.ParentClaimDetail_id 

我實現在NHibernate的這個查詢作爲

ICriteria query = session.CreateCriteria(typeof(ClaimDetail), "cd") 
    .CreateAlias("ParentClaimDetail", "cds", NHibernate.SqlCommand.JoinType.LeftOuterJoin); 
query.SetProjection 
       (
        Projections.ProjectionList() 
         .Add(Projections.Property("cd.ParentClaimDetail.Id"), "sks") 
         .Add(Projections.Property("cd.Id"),"cdid") 
         .Add(Projections.Property("cds.DateCreated"), "dc1") 
         .Add(Projections.Property("cd.DateCreated"), "dc2") 
         .Add(Projections.Property("cds.ParentClaimDetail.Id"), "cds") 
         .Add(Projections.Property("cds.Id"),"cdsid") 
      ); 

但這創建標準創建查詢爲

SELECT cd.ClaimDetailId , 
cd.ParentClaimDetail_id , 
cds.ClaimDetailId , 
cds.ParentClaimDetail_id , 
cds.DateCreated, 
cd.DateCreated 
FROM ClaimDetail AS cd left JOIN ClaimDetail AS cds ON 
cd.ParentClaimDetail_id = cds.ClaimDetailId 

任何人都可以幫助我。

在此先感謝

它看起來像你想要使用命名查詢。指定的查詢進入映射XML，您可以將輸入提供給它。另外，您可以選擇一個自定義類來表示結果數據的實體。
