A lots thanks to Roseindia for this tutorial, but on execution I've: NULL
and no change in my database.
Then I've addded the "Transaction instructions" and I've changed the "hql" String in:
delete Insurance where id = 2
and on execution I've:
Hibernate: delete from INSURANCE insurance0_ where (id=2) Exception in thread "main" org.hibernate.exception.SQLGrammarException: could not execute update query .... Caused by: java.sql.SQLException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'insurance0_ where (id=2)' at line 1"
