Re: [eclipselink-users] How to compare entities from two different databases and replace one with the other?
|
You can use dbunit to compare data in tables. Ant tasks are simple,
but you can do it programmically as well.
http://www.dbunit.org/anttask.html#databasecompare
http://www.dbunit.org/anttask.html#partialcompare
You can also use dbunit to export data from one database and import it
into another database, again, either using ant or java code.
