詳細
Description
Equivalent to the Hibernate
refresh method.
Re-reads the state of the given instance from the underlying database. It is inadvisable to use this to implement long-running sessions that span many business tasks. However this method is useful in certain special circumstances. For example
- where a database trigger alters the object state upon insert or update
- after executing direct SQL (e.g. a bulk update) in the same Session
- after inserting a Blob or Clob
