Hi all,
I try to map the following:
A class A (attributes a_id, b) has a 1:1 association (unidirectional) to
class B (attribute b_id). The association is persisted in a join table AB
(attributes a_id, b_id, discriminator). The 1:1 association can be found
with the aid of the discriminator (lets say discriminator must be 'X'). The
incomplete solution (for the mapping file A) might be:
<join table="AB"
optional="true">
<key column="a_id"
unique="true"/>
<many-to-one name="b"
column="b_id"
not-null="true"
unique="true"
class="B"/>
</join>
How can I add the additional condition "discriminator='X'" to the mapping ?
Thanks for any help,
Mike
