database field name 'version' causes ClassCastException while building session
factory
--------------------------------------------------------------------------------------
Key: HHH-3002
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3002
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.5
Environment: Hibernate 3.2.5, Java 1.6.0_03, MySQL 5.0.41
Reporter: Patrick Burke
Attachments: out.hib4
When a database table contains a field named 'version', like his one:
DROP TABLE IF EXISTS `tester`.`software_package`;
CREATE TABLE `tester`.`software_package` (
`software_id` int(11) NOT NULL auto_increment,
`version` varchar(100) default NULL,
`name` varchar(100) default NULL,
`root_file_id` int(11) default NULL,
PRIMARY KEY (`software_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
The following error is thrown:

Patrick Burke commented on HHH-3002:
------------------------------------
I think you misunderstood the problem. I didn't make a version field.. I made a
field named version. MySQL has no concept of a VERSION field that I'm aware of. I
should be able to make a field I named 'version' any type I want.. I understand
where your confusion comes from because all numeric types implement the version interface
in hibernate, but this is definitely a bug. Hibernate should know the difference between
a version field and a field named version.

---------------------------------------
if Hibernate try to use a VersionType it's because in your mapping there is a
<version /> element. Othewise it does not guess.
Now Hibernate *tools* will try to guess when reverse engineering, but this a different...
tool, not hibernate core.

Chin Hsu commented on HHH-3002:
-------------------------------
I don't know if you use reverse engineering tool to generate the hbm.xml but I did and
have the exact same exception trace. for a database table with a column named version,
the generated hbm will have the field defined in a version element:
<version name="version" type="string">
<column name="VERSION" length="20" />
</version>
when it should be:
<property name="version" type="string">
<column name="VERSION" length="20" />
</property>
manually fix the hbm.xml file solves the problem. I think this maybe a bug on the reverse
engineering tool?
