[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5856) Update only saves back changes

Update only saves back changes ------------------------------ Key: HHH-5856 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5856 Project: Hibernate Core Issue Type: New Feature Components: core Environment: N/A Reporter: Darren S. Eyers When a record is saved back to the database all the fields are sent back to the database. If one was going to do SQL instead they would just update the columns that have changed. This means at the moment all columns are updated/sent back to the DB which affects performance in both the DB and network. Wondering if there is any way possible to record which fields have been changed. Thinking maybe something could be done with AOP, but looks like extra variables/parameters would be needed. On save there could be an extra version of save which has a boolean or list of fields that have changed and then only update those fields. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
