I connect listeners to events in order to make some table auditing. My problem is that after the merge() (or whatever operation I use) session is flushed and it triggers events for several objects. For example, if my session has 5 objects (connected with some cascades) I get several events triggered, even when only one of them is actually modified.

Hibernate won't trigger more SQL than neccesary, but at this point I don't know whether my event can distinguish modified objects, because it's important for me triggering auditing only at modified tables.

Is there something like ...willThisObjectTriggerSql(event.getObject())?

Thanks in advance!!

You can check if a specific ISession contains any changes by calling:



for specific instances you can implement an Interceptor to handle the auditing a simple example is found in the nhibernate reference manual chapter 9.10
