I need some help understanding hibernate behavior -

I have to select a large collection using IDs in an IN (x,y,...z) clause. There is a limitation as to the number of elements I can use so I have had to resort to breaking the list into parts.

Between groups, the data is verified and, in some cases, manipulated.

When I go to get the next group, objects which have been manipulated are marked to be updated on the flush.

Why does this happen and how do I prevent it?

Answer is in your question



So when hibernate does a flush it does dirty checking ( automatic ) and syncs up the data with the db.

As to second question

you can do

session.setFlushMode(FlushMode.NEVER)
