[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3711) Add reverse operation support

[jason shi (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32938#action_32938 ] 

jason shi commented on HHH-3711:
--------------------------------

For Example, there is entity named CustomerAccount with properties:customerId & amount

At Rev 0, create a record: CustomerAccount (customerId =1,amount=100)
At Rev 1, change value of amount to 200, CustomerAccount (customerId ,amount=200)
At Rev 2, change value of amount to 300, CustomerAccount (customerId ,amount=300)

If the customer don't want the change of Rev2, then we need restore Rev1 from audit table to original table, 
and insert a new Rev 4 to audit tables: CustomerAccount (customerId ,amount=200)

This reversal operation is base on the single CustomerAccount, not whole database reversal
