Fluent NHibernate to query stored procedure without an hbm.xml mapping

Question

Is there any way to query stored procedure in Fluent Nhibernate without creating an hbm.xml file mapping?

Answer 1

some good answers here however I want to make a more generic solution where I can pass in the object I want out and dynamically set my stored procedure parameters.

 public RequestList FetchExport(Integration_ExportType exportType)
     {
         var returnRequest = new RequestList{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());

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

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

         }
     }

An example of a generic type - mapped to the output of the stored procedure & create an un-mapped object for the stored procedure parameters that gets attached to a patent object.

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; }
}

Finally how it's implemented

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