you could use where clause, filters, views or create a dummy subclass.
my point is, it should include the discriminator column in the select clause, so that users don't have to resort to these work arounds. having built several ORM in the past, that's how I would do it. If anyone knows which file to look at, I'm happy to take a look and make a patch for it. peter On Sep 26, 2:40 pm, "Tuna Toksöz" <[EMAIL PROTECTED]> wrote: > I think this is where filters come into play? > > On Fri, Sep 26, 2008 at 9:31 PM, Jon Palmer <[EMAIL PROTECTED]>wrote: > > > > > > > Can't you just specify a Where clause in the definition of the single > > class mapping. > > > -----Original Message----- > > From: [email protected] [mailto:[EMAIL PROTECTED] On > > Behalf Of Peter Lin > > Sent: Friday, September 26, 2008 11:29 AM > > To: nhusers > > Subject: [nhusers] Re: Discriminator bug > > > the reason is simple. what if I'm reading data from an existing > > database, which uses the concept of a discriminator with > > address_type_code. what if the address table has entries with > > different address_type_code values? > > > If I only want to get a specific type of address from the database and > > I don't have a subclass, NHibernate wouldn't return the correct > > result.
