[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3707) Generate wrong CRUD SQL for joined-subclasses of union-subclass
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 (?, ?, ?);
