Re: [eclipselink-users] Does Eclipselink/Toplink generate back out SQLs?
|
No, EclipseLink does not support this.
Using events as you are is probably your best means.
EclipseLink does have full history support, which is somewhat similar.
History maintains a separate table of all changes that have occurred so that
you could query or restore any entity to any point in time.
