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.
