Question

how do I remove all records associated to one user, for example I want to remove 5 records in my database that owner is currently logged in user.
Here is my code:

public void deleteOrders() {

    Authentication auth = SecurityContextHolder.getContext()
            .getAuthentication();
    String user = auth.getName(); // get logged in username
    getHibernateTemplate().delete(
            "FROM " + Orders.class.getName() + " WHERE username='" + user
                    + "'");
}

Im trying something like this but it fails and I can’t move on. How to do it right?

Answer 1

HibernateTemplate.delete() takes an entity instance to delete as argument. It doesn’t take a HQL query.

Use bulkUpdate() to execute a delete query. Or even better, forget about HibernateTemplate, which is deprecated, and use the Hibernate API directly.
