Unable to execute stored procedure using named query in nhibernate

Question

I am facing strange problem while executing stored procedure using nhibernate. When I am going through stack trace then I got Index Out Of Range exception and name of property / column. I research on google and stackoverflow and found that if any property is mapped two times then it cause problem. I checked all mapping but nothing seems to be helpful for me. Here I am writing all hbl files and codes which I am using.

Hbm file code

I am using following code to call sp.

                       .SetParameter("CustomerActive", 2)
                       .SetParameter("CompanyID", Guid.Parse("3C5F1D66-75F3-4762-BAA1-6A0ADA8D6DD4"))
                       .SetParameter("PropertyID", Guid.Parse("53C4B765-C1B1-4353-98CB-AC9FBCE84F0C"))
                       .SetParameter("DateFrom", DateTime.Parse("5/1/2001"))
                       .SetParameter("DateTo", DateTime.Parse("4/24/2013"))
                       .SetParameter("InvoiceTypes", "Manual")
                       .SetResultTransformer(new AliasToBeanResultTransformer(typeof(tARCustomer)))
                       .SetResultTransformer(Transformers.ToList).List();

Except for that I tried so many combination but I am not able to solve it. I have following stored procedure.

alter PROCEDURE [dbo].[ar_tARCustomer_ReadOverdueByContext]  

  @CustomerActive  int,      
  @CompanyID   uniqueidentifier,   
  @PropertyID   uniqueidentifier,   
  @OverdueDateFrom  datetime,   
  @OverdueDateTo  datetime,   
  @InvoiceTypes   varchar(100)

SET NOCOUNT ON;  -

SELECT fName
from tARCustomer 

One more thing I want to say that when I am using select * from tARCustomer then this procedure is worked for me but when I am using select fCustomerID from tARCustomer then it gives error.

I don't know why it happens but am not able to solve it. Please help me to solve out this problem as soon as possible,

Here I am putting stack trace of exception.

Thanks.

Answer 1

When you use the AliasToBeanResultTransformer on the result of your query the columns returned in the query must map one to one with the properties on the class you are loading with data.

Your query posted above only returns a single column fName1 - it is missing all of the other properties of your class tARCustomer .

The thrown exception is telling you the issue - that it cannot find result column fCustomerID . To illustrate modify your select statement to include this and re-run it, the exception will then highlight the next missing field.
