I really want to know more about the update, export and the values that could be given to hibernate.hbm2ddl.auto
I need to know when to use the update and when not? And what is the alternative?
These are changes that could happen over DB:
- New tables
- new columns in old tables
- columns deleted
- data type of a column changed
- a type of a column changed it attributes
- tables have been dropped
- values of a column has changed
- In each case what is the best solution?
