Hi friends :

Anyone could tell me if hibernate cache object[] ? For example: I have a query like this:

Code:

String hql="select a.name,b.age,c.email from A a,B b,C c ";
List list=session.find(hql);
for(Iterator iter=list.iterator();iter.hasNext();){

   Object[] o=(Object[]) iter.next(); <-- Will Hibernate cache this Object[]?
...........................................
..........................................

I want to know whether hibernate will cache the object[] if I use session.iterator or session.find. Thks!

If I use HQL " from A a,B b,C c " ,hibernate will cache A,B and C POJO object. But if I select some property of this Class ,hibernate will cache them too? Help

hibernate caches *entities* and if you enable it hibernate also have a querycache that can cache *values*.

well - it depends on how long you have your session open ;)

...and I would really recommend you to read the hibernate action sections about caching, just to be sure you know the ramifications of different caching strategies.

Ok . query cache is a good idea. Hibernate in Action, I will try it. :)
