"after the query has returned from the database"

I have a lot of fighting against Spring / Hibernate for this. It doesn't let me do cartesian product because the query builder thinks it needs a cartesian product, I can't select only some of the columns without making a whole new data structure while fighting the ORM that thinks one table = one class, can't query from a joined table.

I don't have any issue with mapping using these query builders like jooq which lets you use generated class from the live db for simple use case and give you other mechanism for querying weird joins or aggregates.

What sort of perks of ORM after the query has returned do you find to be helpful?
