> 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?
