Question

有没有办法在不创建hbm.xml文件映射的情况下在Fluent Nhibernate中查询存储过程？

Answer 1

我假设您使用标准

Session.GetNamedQuery(....

相反，您可以使用

var result = Session.CreateSQLQuery("exec MyStoredProc :pUserId, :pIsLocked")
                    .AddEntity(typeof(MyDomainObject))
                    .SetParameter("pUserId", userId)
                    .SetParameter("pIsLocked", isLocked)
                    .List<MyDomainObject>();

这允许您调用存储过程，但仍然可以获取域对象（或列表）而无需.hbm.xml文件。

在我的情况下，你应该有一个返回结果集的类，它是GameActivity类



    public class GameActivity
    {
            public virtual DateTime Date { get; set; }
            public virtual string GameRoundId { get; set; }
            public virtual int GameProvider { get; set; }
            public virtual string GameName { get; set; }
            public virtual decimal RealBet { get; set; }
            public virtual decimal RealWin { get; set; }
            public virtual decimal BonusBet { get; set; }
            public virtual decimal BonusWin { get; set; }
            public virtual decimal BonusContribution { get; set; }
            public virtual int IsRoundCompleted { get; set; }
            public virtual int IsRoundCancelled { get; set; }
    }

调用存储过程“GetMemberGameActivity”以获取列表



    var result = session.CreateSQLQuery("exec GetMemberGameActivity :mToken, :StartDate, :EndDate")
                        .SetResultTransformer(Transformers.AliasToBean())
                        .SetParameter("mToken", token)
                        .SetParameter("StartDate", startDate)
                        .SetParameter("EndDate", endDate)
                        .List().ToList();

这里有一些好的答案，但我想制作一个更通用的解决方案，我可以传入我想要的对象并动态设置我的存储过程参数。

 public RequestList<T> FetchExport<T>(Integration_ExportType exportType)
     {
         var returnRequest = new RequestList<T>{Success = true};
         try
         {
             string sql = "EXEC "+exportType.StoredProcedure+" :@" + string.Join(", :@",exportType.Parameters.GetType().GetProperties().Select(pinfo => pinfo.Name).ToArray());

             var session = Session.CreateSQLQuery(sql).SetResultTransformer(Transformers.AliasToBean<T>());

             foreach (var parameter in exportType.Parameters.GetType().GetProperties())
             {
                 session.SetParameter("@" + parameter.Name, parameter.GetValue(exportType.Parameters,null));
             }
            returnRequest.Obj = session.List<T>().ToList();

             return returnRequest;
         }
         catch (Exception exception )
         {
             returnRequest.Success = false;
             returnRequest.Message = exception.Message;
             returnRequest.Exception = exception;
             return returnRequest;

         }
     }

泛型类型的一个示例 - 映射到存储过程的输出＆amp;为附加到专利对象的存储过程参数创建一个未映射的对象。

public class Integration_ExportRERW_Scores 
{
    public string SchoolId { get; set; }
    public string SSID { get; set; }
    public int LessonId { get; set; }
    public int ClassPeriod { get; set; }
    public string TeacherId { get; set; }
    public string LessonTitle { get; set; }
    public int RW4ComprehensionScore { get; set; }
    public int RW4WordPowerScore { get; set; }
    public int REComprehensionScore { get; set; }
    public int REVocabularyScore { get; set; }
    public int RE2ComprehensionScore { get; set; }
    public int RE2VocabularyScore { get; set; }
}

public class Integration_ExportRERW_Scores_Parameters
{
    public int DistrictId { get; set; }
}

最后如何实施

 var export = service.ListSubscriptions().First().Export;
         var parameters = new Integration_ExportRERW_Scores_Parameters
         {
             DistrictId = 12060
         };
         export.Parameters = parameters;
         var fetch = service.ExportData<Integration_ExportRERW_Scores>(export);
