In one-to-many relationship (Set, Map, List), let <key> accept <formula> as an alternative to <column>. --------------------------------------------------------------------------------------------------------- Key: HHH-944 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-944 Project: Hibernate3 Type: New Feature

Versions: 3.1 rc3 Reporter: Etienne Laverdiere

As explain in http://forum.hibernate.org/viewtopic.php?t=947249&highlight=&sid=... and alternatively in http://forum.hibernate.org/viewtopic.php?t=947145&highlight=&sid=..., it would be nice if the <key> inside a SET or any collection (one-to-many relationship) could accept a <formula> instead of the column: Example: <set name="childrens" lazy="true" inverse="true"> <key foreign-key="FinancialTransit"> <formula>ANY SQL</formula> </key> <one-to-many class="com.eg.Children" /> </set> instead of : <set name="childrens" lazy="true" inverse="true"> <key foreign-key="key1"> <column name="key2" scale="10" precision="0" not-null="false" unique="true" /> </key> <one-to-many class="com.eg.Children" /> </set> It would necessitate to patch the class AbstractCollectionPersister and modify the DTD of hibernate mapping.
