hibernate.hbm2ddl.auto consult and doubts

Yes, and I don't believe in XP.



Ok, agreed.

I do not believe in XP as well, but it works. Sometime. And anyway this or that flavor of agile development is usually a best possible choice (with some exceptions). Myself have used these agile approaches many years before the term was coined. Somewhen from early 80-s. And it works.

Write the new/update old files, generate scripts to update database schema with hbm2ddl.update by redirecting output to the file (it is described in the Hibernate reference, 20.1.5, 20.1.6),

Because this topic is not such important, the Hibernate authors can not imagine even in nightmare that somebody will try it in production

More seriously, Reference is just reference, strictly technical document with probably few examples. For all other things - books, articles, etc. And "Java Persistence with Hibernate" is a must for anybody who plan serious development with Hibernate.

And one more - the whole philosophy of Hibernate - we provide you with log of options, it is your responsibility to decide which suit you, weigh advantages and risks yourself. BTW, probably you have noticed that Hibernate forums (unlike Spring ones) are not so much supportive.

This is quite typical situation but nobody add such change directly to production. So you use this option but not for direct database update, but for script generation. apply this script in development and or test environment, test results and only then apply tested script to production. But we have already discussed this before

i prefer the first edition, Hibernate in Action

Great book and not so fat as new edition, but Hibernate 2.0 based. Many things have changed. And some things are really better explained in new version.
