Hi,
Me again. Is there an EAnnotation I can use to set a "unique-key" =

constraint on two "many-to-one" associations in Hibernate? Basically, I=
=

want to generate a mapping similar to the following:

:
:
<many-to-one name=3D"roadGroupMembership" entity-name=3D"user_rgm" =

cascade=3D"merge,persist,save-update,lock,refresh" lazy=3D"false" =

insert=3D"true" update=3D"true" not-null=3D"false">
<column not-null=3D"false" unique-key=3D"user_rgm" =

name=3D"`membership_roadgroupmembership_id`"/>
</many-to-one>
:
:

<many-to-one name=3D"userAccount" entity-name=3D"UserAccount" =

cascade=3D"merge,persist,save-update,lock,refresh" lazy=3D"false" =

insert=3D"true" update=3D"true" not-null=3D"true">
<column not-null=3D"false" unique-key=3D"user_rgm" =

name=3D"`useraccount_useraccount_id`"/>
</many-to-one>
:

Thanks,
Stephen.

Hi Stephen,
This is supported for eattributes but not yet for ereference (many-to-one). Please enter a bugzilla
for this.

The annotation will then be:
annotation on the eclass:
@Table(name="MYITEMTABLE" uniqueConstraints={@UniqueConstraint(columnNames={"MYSTR", "MYINT"})})

and then you would need a joincolumn annotation on the manytoone to set the names to MYSTR and MYINT.
