I met a problem when try to map an one-to-one relationship in a single
table.
For example there're two entities (Product and ProductDetail):
public class Product
{
public virtual int ProductID { get; set; }
public virtual string Name { get; set; }
public virtual float Price { get;
Hi,
On a mapped entity I have a Dictionarystring, string that is mapped
successfully for data retrieval as follows:
map name=Properties table=EntityProperty
key column=EntityID/
index column=Title type=System.String/
element column=Value type=System.String/
/map

I have a question about the way session.Save works.
I have a session, I open a transaction over this session, and then
commit the transaction.
There are two different things I am doing within session and
transaction:
1. Load an entity and add another entity to one of its collections.
This works
To use associations your table should contain a foreign key. In your
current table definition you should use component, and the mapping
like this:
class name=Product table=Product
id name=ProductID column=ProductID
generator class=hilo/
/id
property name=Name/
But component mapping cannot implement lazy load. Any ways to get both
single table one-to-one mapping and lazy load?

SDS is not really a DB, at least not in the RDBMS sense. It's not

I agree with Fabio. The table needs to be selected anyway. It does not
make sense to only read half the columns from the table, and read the
rest in another query. Usually, the most expensive are db roundtrips
and joins.
