Question

I see there are two ways to create update query in Hibernate. First you can go with the standard approach where we have hql like:

Query q = session.createQuery("update" + LogsBean.class.getName() + " LogsBean " + "set LogsBean.jobId= :jobId where LogsBean.jobId= :oldValue ");
            q.setLong("jobId", jobId);
            q.setLong("oldValue", 0);
            return q.executeUpdate();

or we can go and run

getHibernateTemplate.saveorupdate(jobId);

Now am getting java.lang.IllegalArgumentException: node to traverse cannot be null! on running first query and am not sure hwo to provide condition in getHibernateTemplate example, i want to update jobIds in log table whose value matches 0 and so i want to run something like

Update logs set jobId = 23 where jobId = 0

Above is the simple sql query that I am trying to run but I want to run this via hibernate, tried couple ways but it is not working, any suggestions?

Update:

As noted by Jeff, issue was not having space after update and so that issue got resolved but still values are not updated, i have updated show_sql true for hibernate and checking what could be the cause of the issue, will be running query generated by hibernate to run again db and see if records are updated.

Just a few things that might help you to resolve this:

• What does .executeUpdate() return, 0 (as it did not update any
  rows)?
• Does it throw a HibernateException that you are
  silently catching or rethrowing?
• Which FlushMode do you have configured?
• Does the update get to the DB? You could switch on the query log for your DB server.
