One-to-one:property-ref to a part of composite-key
--------------------------------------------------
Key: HHH-4013
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4013
Project: Hibernate Core
Issue Type: Improvement
Reporter: Sandeep Vaid
I have 2 classes viz. Product and ProductBasic having one-to-one relationship
Product is mapped to a table PRODUCT which has PRODUCTID as PK.
ProductBasic is mapped to a table PRODUCTBASIC which has PRODUCTID,USECODE and STARTTTIME
as composite key.
My database is legacy and i cannot change it.
I get the one-to-one relationship by applying the condition as:
PRODUCT.PRODUCTID=PRODUCTBASIC.PRODUCTID and USECODE='008' and STARTTIME <
CURRENTIME < ENDTIME..
My database values are such that if i apply this condition i will only get once
record..
In Product.hbm.xml:
<class name="Product" table="PRODUCT"
<id name="pid" type="string" column="PRODUCTID"
length="10">
<generator class="assigned"></generator>
</id>
<one-to-one name="productBasic" class="ProductBasic"
constrained="true" outer-join="false" cascade="save-update"
property-ref="activeProductBasic" >
<formula>PRODUCTID</formula>
</one-to-one>
</class>
In ProductBasic.hbm.xml
<class name="ProductBasic" table="PRODUCTBASIC">
<composite-id name="compProductBasic"
class="CompProductRelatedAssociations">
<key-property name="productId" column="PRODUCTID"
type="string" length="10" />
<key-property name="useCode" column="USECODE"
type="string" length="10" />
<key-property name="startTime" column="STARTTIME"
type="timestamp"/>
</composite-id>
<properties name="activeProductBasic">
<property name="compProductBasic.productId"
column="PRODUCTID" type="string" length="10"
insert="false" update="false"/>
</properties>
</class>
but this compProductBasic.productId is giving me error...
