DerbyDialect javadoc
--------------------

         Key: HHH-1915
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1915
     Project: Hibernate3
        Type: Improvement

  Components: documentation  
    Versions: 3.1.2    
 Environment: Hibernate 3.1.2, Derby 10.1.2.1
    Reporter: Brian Bonner


Hibernate 3.1.2's DerbyDialect seems to work around some issues in Derby's JDBC 3.0 Support, but it's not clearly documented in the Javadoc why it is the case.

For example:

Derby does support Identity columns  (http://db.apache.org/derby/docs/10.1/ref/rrefidentityvallocal.html) and it looks like the Dialect includes this, but then it uses the TableHiLoGenerator instead of the IdentityGenerator.

I assume it's to work around this problem:

http://forum.hibernate.org/viewtopic.php?t=951233&highlight=derby+native

but I can't say for certain.  

I've created a JIRA on Derby:  https://issues.apache.org/jira/browse/DERBY-1518  for the preparedStatement issue highlighted here, with the assumption that this is the reason.
