Hi everyone,
I'm trying to set up the mappings between a number of tables. I'd like to be able to retrieve them (or large sections of them) with one call to the database instead of one call for each relationship. Is there any way to get Hibernate to do this?
Thanks
- Adam

Well, that's what "eager" fetching is all about. Hibernate prefers "lazy" fetches, because complex tables with lots of relationships can potentially drag in the world and its dog and load all of it into memory at once. However, you can tweak the fetch process if you know that certain relationships will always go together.

One of the most odious afflictions that Business has inflicted on the modern English language is "pro-active". Most of the time it's simply redundantly used in place of the simple old word "active". And a good deal of the rest of the time it means "You're not overworked enough yet, so go out and find more!"
