Hi,

What is the use of hbm2ddl.auto setting?

The hbm2ddl.auto property is used to validate, update and export the database schema at the time of creation of SessionFactory.

If you change the definition of Entity class then Hibernate can update the database schema if appropriate value of hbm2ddl.auto is set correctly.

Hibernate hbm2ddl.auto values

The possible values for this property are:

validate: Its used to validate the schema but no changes are made to database.

update: If the value is set to update then it will update the database schema.

create: creates the schema, destroying previous data.

create-drop: If this property create-drop is provided then it drops the schema when the SessionFactory is closed explicitly. And at the time of SessionFactory startup it is re-reated.
