Generate wrong CRUD SQL for joined-subclasses of union-subclass --------------------------------------------------------------- Key: HHH-3707 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3707 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: Hibernate V3.2.6, Oracle 11g Reporter: David Wang Attachments: src.zip We use extension table to customerize our base line. Create one joined-subclass to the existed union-subclass in the project. For simple, I create simple sample to demo the error. UnionTableOne and UnionTableTwo are union-subclass of UnionTable. UnionTableOneExt is joined-subclass of UnionTableOne. See the attached files. Here list the hebernate mapping file. <hibernate-mapping package="union"> <class name="UnionTable" entity-name="UnionTable" abstract="true"> <id name="unionId" type="java.lang.Integer"> <column name="UNION_ID" /> <generator class="assigned" /> </id> </class> <union-subclass name="UnionTableOne" extends="UnionTable" entity-name="UnionTableOne" table="uniontableone"> <property name="oneName" column="ONE_NAME"></property> </union-subclass> <union-subclass name="UnionTableTwo" extends="UnionTable" entity-name="UnionTableTwo" table="uniontabletwo"> <property name="twoName" column="TWO_NAME"></property> </union-subclass> <joined-subclass name="UnionTableOneExt" extends="UnionTableOne" entity-name="UnionTableOneExt" table="uniontableone_ext"> <key column="UNION_ID"></key> <property name="extName" column="EXT_NAME"></property> </joined-subclass> </hibernate-mapping> When I create one UnionTableOneExt object, the generated SQL is insert into uniontableone_ext (ONE_NAME, EXT_NAME, UNION_ID) values (?, ?, ?); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
