> ------------------------------------------------------------------------------------------------------------
>
> Key: HHH-3783
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3783
> Project: Hibernate Core
> Issue Type: Bug
> Environment: HIbernate 3.2.5.ga; Database: Oracle
> Reporter: Soorjith Kombilath
>
> I have a hibernate object with composite key -
> <composite-id>
> <key-many-to-one name="parent" column="PARENT_NUMBER" class="com.test.entity.impl.ParentImpl" />
> <key-property name="restraintCode" column="RESTRAINT_CDE" type="string" />
> </composite-id>
> In database there is a unique index on PARENT_NUMBER.
> Parent object may contain a collection of chjld objects.
> Whenever a child object is removed and a new child object is added, it throws unique constraint violation error.
> When I check the queries generated, hibernate is executing the queries for INSERT before executing DELETE. Is there any way to enforce DELETE before INSERTS? or am I missing to specify some attribute in my mapping?
