Hibernate version: 2.1.6

Hi everybody!

What is Query.scroll method good for? The ScrollableResults interface doesn't have a method for retrieving the whole persistent object, just an array of values. How do I construct the object from a particular row?

From what I read in the forum, it is an alternative to setFirstResult+setMaxResult, but what are the advantages/disadvantages of using one or the other?

Thanks for help.

Are you performing a scalar query? If not, the "whole persistent object" is already retreived for you as you scroll through the results. It's simply the first (and only) dimension in the array.

Thanks steve, I didn't realize that. Now it's working.
