Hy,

I have a doubt about hibernate. When do i have to use the merge method? I only use update,save, list ... but never merge. Any help is good.

If you pass an object into a session where a persistent object exists with the same identifier, it will update the persistent object. If the persistent object with the same identifier does not exist, it saves the object.

I don't use it that much either, but it has its uses.

Take a look ate the documentation:

Automatic state detection

The use of save , update , saveOrUpdate and merge is explained.
