How to delete all rows? Do I need to retrieve all rows from database, and then remove one by one using EntityManager? If yes, it is not efficient. If using SQL, just one SQL statement to delete all rows. does EJB QL support DML such as delete?
Thanks. Dave

You now have a batch delete.
Read in documentation.
