Hi,

I am new to Hibernate, my application needs one-to-one mapping of two tables having different primary keys. Please let me know, how to do this.

Thanks,

Kum

assuming...

Table A with column id
Table B with column id and fk (foreign key to A.id)

Then, the mapping could be
<class name="A" table="A">
<id name="id" type="integer"/>
<one-to-one name='to' class="B" property-ref="fk"/>
</class>

<class name="B" table="B">
<id name="id" type="integer"/>
<property name="fk" type="integer"/>
</class>

Thanx a lot Anar.

What if in class B
id and fk columns form the composite key and fk column is also the foreign key referencing table A?
How will the mapping look like

But how can we do this with annotation ?
I am using the hibernate annotation documentation that says to do
this :

This seems to be very simple. But it does not work !
I have a cannot simultaneously fetch multiple bags exception ?
