Part of Composite-Id is foreign Key:How specify in Mapping? ----------------------------------------------------------- Key: HIBERNATE-117 URL: https://jira.jboss.org/jira/browse/HIBERNATE-117 Project: Hibernate Issue Type: Feature Request Reporter: Sandeep Vaid Assignee: Steve Ebersole I have 2 classes viz. Product and ProductBasic having one-to-one relationship class Product{ String productId; ProductBasic productBasic; } class ProductBasic{ String productId; String useCode; TimeStamp startTime; Product product; } 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. Also PRODUCTID (of PRODUCTBASIC table) is the foreign key referencing PRODUCT table... How can i define my one-to-one mapping considering ProductBasic.productId should get its value from Product.productId ? <composite-id> <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" /> <composite-id> In this only productId is the foreign key.. I am aware that i can use a <generator> tag (with class="foreign") inside <composite-id> but i guess it will generate the value for entire composite-id and not just a field of it. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
