I would like to start off saying that this board has saved me many
hours over the last few years. Most of the time my issues are simple
to look-up here or stackoverflow but this time the problem is
stickier.
I have two oracle Schema for defining facilities, foo and bar.
* bar depends on foo and in some cases extends it.
* foo cannot see bar.
* foo and bar are in separate assemblies
* foo.FACILITY is the base class that i want to extend
the mapping for foo.FACILITY follows
<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="foo"
namespace="foo" schema="FOO">
<class name="Facility">
<id name="Id" >
<column name="ID"/>
<generator class="increment" />
</id>
<many-to-one name="Address" column="ADDRESS_ID" cascade="save-
update" />
<many-to-one name="Location" column="LOCATION_ID" cascade="save-
update" />
<property name="NumberOfAcres" column="NUMBER_OF_ACRES"
type="Decimal" />
</class>
</hibernate-mapping>
the problem stems from the fact that i don't have a bar.FACILITY table
to use for a joined-subclass. i have several many-to-many and one-to-
many relationships between tables in bar and foo.FACILITY
forgive the incorrectness of what i am about to show, i am really not
sure how to map this.
the bar mapping:
<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping namespace="bar" assembly="bar"
xmlns="urn:nhibernate-mapping-2.2" auto-import="false">
<subclass name="Facility" extends="foo.Facility" >
<bag name="Programs" table="FACILITYPROGRAM" inverse="true"
lazy="true" cascade="delete">
<key column="FACILITY_ID" />
<many-to-many class="ProgramLookup" column="PROGRAM_FK"
unique="true"/>
</bag>
</subclass>
</hibernate-mapping>
I don't have a discriminator in this relationship so i know that
subclass is incorrect. also this is a stable production dataset so i
am not able to afford to make major changes.
Thank You,
Chris Woerz
