A stateless session is a lower-level abstraction that is much closer to the underlying JDBC.Stateless Session session = session Stateless Session(); Transaction tx = session.begin Transaction(); Scrollable Results customers = Named Query("Get Customers") .scroll(Scroll Mode.An HQL bulk operation might result in multiple actual SQL statements being executed (for joined-subclass, for example).The returned number indicates the number of actual entities affected by the statement.Hibernate Template.execute(Hibernate Template.java:151) org.hibernate.

Max File Size = 4096KB # Set the number of log files (0 means no backup files at all) log4j.appender.hibernate Log. Max Backup Index = 1 log4j.appender.errors Log.layout = org.apache.log4j. Conversion Pattern = [%p] [%d] [%t|%c] %m%n First, I read an object via Hibernate, update it in the code, and then call a dao’s update method to persist it – pretty simple.
Max Backup Index = 10 # Append to the end of the file or overwrites the file at start. Append = false log4j.appender.hibernate Log.layout = org.apache.log4j. However while debugging it step by step, after executing the Hibernate update query, in a log, I saw: So the Hibernate did not update the object due the fact that it thought that another object was already associated with this Hibernate session.
Meaning the flexibility is there, but the framework should not encourage its clients to get inside framework’s stereotypes.
This way framework’s code (internal stereotypes) can alter, and still have “older version clients” running without (significant) change.
