Hi I have newly subscribed to this list. Some time ago I submitted patches to the Hibernate Jira to address a couple of issues. https://hibernate.onjira.com/browse/HHH-5553 The first is the use of local time for the @Version field and suggest using the UTC function instead on Oracle https://hibernate.onjira.com/browse/HHH-5554 The second relates to providing a mechanism for customising the column aliasing scheme. This is due to widespread use of '_' in identifiers on Oracle which is also used as a truncation marker by Hibernate making generated queries difficult to read. Is there any interest in applying either of these two fixes, if so, I can update them for the current Hibernate 4.0.0 codebase if necessary. With thanks, Chris
