Hibernate version:3.2.4.sp1

Hi guys,
Can i decide lazy/non-lazy loading at runtime, without declaring it in the mapping files?

As far as I know, you can't... Once the collection is declared lazy or eager, that will be it's behavior. There's a way of fetching lazy (not extra-lazy) collections, that is calling the collections method size(), forcing hibernate to load it any time you want (within a valid session).

Thanks,
but i know this. I'm asking for is there any way to load a collection in a NON-LAZY manner when it is defined as LAZY in the mapping file. I need this because most of the time my requirement is lazy loading but few times it is not, so i want to take decision at runtime. Is there any way? If not can it be possible to add this feature to next version?

If you're loading a single entity you can use HQL or criteria to eager populate a collection.

e.g.


This will populate the kittens collection of Cat using an sql join.

If Kittens has also collections how to eager initialize/over-ride the lazy=true configuration. Can you please help on this

Thanks

Try this:


Don't forget that, depending on your data, its sometimes more efficient to issue sub-selects rather than adding another join to the query.
