Store procedure (oracle)

I try to get data from store procedure in oracle DB (in sqlserver  its work well).

I get the all list of records(15)  but the data of the all records is the same, The all records equal the first record.

someone know where I am mistake?

Here is the code:

DB code:

create or replace procedure GetTestTable(results out SYS_REFCURSOR) is

begin

  open results for

       select * from testtbl;

end GetTestTable;

Entity code:

[Serializable]
  [System.CodeDom.Compiler.GeneratedCode("LightSpeedModelGenerator", "1.0.0.0")]
  [System.ComponentModel.DataObject]
  [CrudProcedure(Select = "GetTestTable")]
  public partial class GettesttableResult : Entity<int>
  {
    #region Fields
  
    private System.Nullable<decimal> _tblid;
    private string _firstname;
    private string _lastname;
 
    #endregion
    
    #region Field attribute and view names
    
    /// <summary>Identifies the Tblid entity attribute.</summary>
    public const string TblidField = "Tblid";
    /// <summary>Identifies the Firstname entity attribute.</summary>
    public const string FirstnameField = "Firstname";
    /// <summary>Identifies the Lastname entity attribute.</summary>
    public const string LastnameField = "Lastname";
 
 
    #endregion
    
    #region Properties
 
 
 
    public System.Nullable<decimal> Tblid
    {
      get { return Get(ref _tblid, "Tblid"); }
      set { Set(ref _tblid, value, "Tblid"); }
    }
 
    public string Firstname
    {
      get { return Get(ref _firstname, "Firstname"); }
      set { Set(ref _firstname, value, "Firstname"); }
    }
 
    public string Lastname
    {
      get { return Get(ref _lastname, "Lastname"); }
      set { Set(ref _lastname, value, "Lastname"); }
    }
 
    #endregion
  }

public System.Collections.Generic.IList<GettesttableResult> Gettesttable()
    {
      ProcedureQuery procedureQuery = new ProcedureQuery("GETTESTTABLE");
      System.Collections.Generic.IList<GettesttableResult> valueToReturn = Find<GettesttableResult>(procedureQuery);
      
      return valueToReturn;
    }

Call to procedure code:

        private static void OracleConsoleTest()
        {
            _contextOra = new LightSpeedContext<LightSpeedModel1UnitOfWork>("default");
            
            using (var uow = _contextOra.CreateUnitOfWork())
            {
 
               IList<GettesttableResult> tmp = uow.Gettesttable();
 
               Console.ReadLine();             

                 }
             }

Most likely the stored procedure is not returning a column named "Id", or is always returning the same value for Id.  In order to materialise entities, LightSpeed needs an Id column containing unique values.  If the procedure is returning a unique key but that unique key is not named Id then you must specify the Identity Column Name on the entity to tell LightSpeed the name of the unique key.
