Boss / sub-ordinate relation ---------------------------- Key: HHH-3451 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3451 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.3.0.GA Environment: JSF JBOSS Hibernate Reporter: PANDITHA L Priority: Trivial I have an employee table and corresponding Class defined with hbm.xml file. I am using a uniq column (user_id) which is not primary key as my requirement demands it. The problem is this table contains a filed boss_01 which references to user_id so making it one-to-many (i.e user_id to boss_01) mapping on self table. Now how can I access the sub-ordinates(childs) of a given employee? I tried in the below fashion. <class name="mfhr.tables.Employee" table="user"> <id name="id" column="ID_" type="java.lang.Long"> <generator class="increment"/> </id> <property name="user_id" column="user_id" type="java.lang.String" /> <many-to-one name="boss_01" column="boss_01" class="mfhr.tables.Employee" property-ref="user_id" not-null="true" /> <set name="children"> <key column="boss_01" property-ref="user_id" /> <one-to-many class="mfhr.tables.Employee" /> </set> </class> but, When checked in db logs sql is trying to select childs with primary key column rather than user_id. Any help in this regard. -- 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
