How to get a single database query?

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

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.
