Update database schema with hibernate

Question

<property name="hibernate.hbm2ddl.auto">update</property>

i can create my database schema, it automatically add properties, constraint, key etc... But what about UPDATE the database schema? If i remove some property from my entities, hibernate doesn't remove it, or if i change some constraint, hibernate doesn't touch constraint already created...

So, there is a way to make hibernate really update the database schema?

Thanks.

No there is not. hbm2ddl is not meant to do a complete management of your schema migrations. It's best if you use it only for additive changes to your schema and hand edit (the generated scripts) for anything else.
