Hi Glenn, I don't think there is an easy way to determine it programmatically, but I can't imagine that it would be very difficult to provide it (through a stored procedure and/or the JMX interface). It would certainly be useful. Please file a JIRA issue so that we can track this feature request: https://issues.apache.org/jira/browse/DERBY -- Knut Anders
