Question

I want to retrieve a object based on 2 id´s.

Is this the right critera for this?

var notes = session
                .CreateCriteria(typeof(Note))
                .Add(Restrictions.Eq("Product", productId))
                .Add(Restrictions.Eq("User", userId))
                .List<Note>();

does this query fetch the notes that belongs to the user and the product?

and does this criteria:

var comments = session
                .CreateCriteria(typeof(Comment))
                .Add(Restrictions.Eq("Product", productId))
                .Add(Restrictions.Eq("IsOwnComment", 0))
                .List<Comment>();
            return comments;

return the comments of the products where the boolean value is 0?

have i done this right?

Answer 1

var notes = session
                .CreateCriteria(typeof(Note))
                .Add(Restrictions.Eq("Product", productId))
                .Add(Restrictions.Eq("User", userId))
                .List<Note>();

This will not work like this. You would need to provide entire entity of association path of Product and User. What you can do is use the special id property:

var notes = session
                .CreateCriteria(typeof(Note))
                .Add(Restrictions.Eq("Product.id", productId))
                .Add(Restrictions.Eq("User.id", userId))
                .List<Note>();

For second example, use Restrictions.IsNull("IsOwnComment")
