Answer 1

You can do INSERT with HQL (Hibernate Query Language):

Statement types

Both HQL and JPQL allow SELECT, UPDATE and DELETE statements to be performed. HQL additionally allows INSERT statements, in a form similar to a SQL INSERT FROM SELECT.

See: HQL and JPQL

To put data into the database the Hibernate way use the EntityManager interface. It has two methods to put data into the database:

<T> T merge(T entity)

void persist(Object entity)
