> This article published on the O'Reilly web site - http://onjava.com/pub/a/onjava/2005/08/03/hibernate.html?page=3 - describes how to implement joins with formulas, using the hbm xml files. We should be able to do the same with annotations:
> <hibernate-mapping>
> <class name="Company" table="Company">
> <id name="id" />
> <many-to-one
> name="defaultContactPerson"
> property-ref="defaultContactPerson">
> <column name="id"/>
> <formula>1</formula>
> </many-to-one>
> </class>
> <class name="Person" >
> <id name="id" />
> <properties name="defaultContactPerson">
> <property name="companyID" />
> <property name="defaultFlag" />
> </properties>
> </class>
> </hibernate-mapping>
