[hbmlint] Detect repeated columns --------------------------------- Key: HBX-815 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-815 Project: Hibernate Tools Type: New Feature Versions: 3.2beta8 Environment: hibernate v3.2, MySQL 5.1.12-beta-community-nt Reporter: David Balažic (verbatim from the forum , http://forum.hibernate.org/viewtopic.php?t=967007 ) Hi! I use hbm2ddl (from Hibernate Tools v3.2 beta 8) to create the DB schema and noticed, that duplicate column names are not detected. Example: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.manning.hq.stein.data"> <class name="TelefonskiImenik"> <id name="id" column="imid"> <generator class="native" /> </id> <property name="izdajatelj" column="col"/> <property name="verzija" column="col"/> </class> </hibernate-mapping> The same thing happens if one column name is implicit : <property name="izdajatelj" column="verzija"/> <property name="verzija"/> If I try to use this mapping with an application, hibernate (v3.2) fails (in both cases) in buildSessionFactory() : Exception in thread "main" org.hibernate.MappingException: Repeated column in mapping for entity: com.manning.hq.stein.data.TelefonskiImenik column: verzija (should be mapped with insert="false" update="false") at org.hibernate.mapping.PersistentClass.checkColumnDuplication(PersistentClass.java:605) at org.hibernate.mapping.PersistentClass.checkPropertyColumnDuplication(PersistentClass.java:627) at org.hibernate.mapping.PersistentClass.checkColumnDuplication(PersistentClass.java:645) at org.hibernate.mapping.PersistentClass.validate(PersistentClass.java:420) at org.hibernate.mapping.RootClass.validate(RootClass.java:192) at org.hibernate.cfg.Configuration.validate(Configuration.java:1026) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1211) at com.manning.hq.stein.Main2.persist_all(Main2.java:284) at com.manning.hq.stein.Main2.main(Main2.java:45) While this is not a severe bug, it would be nice to detect it as early as possible. -- 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
