Updating modified rows of dataset

Hi Dmitry,

We are examining to grab data from our Oracle database and moving it to another location (S3 or a database).

Is there an easy way in EasyMorph to update the modified rows since last refresh and add/delete rows in the dataset that was modified since the last refresh ?
We will need this kind of operation for other projects as well, so If you could post a reusable project on the forum, this would be great also for other users.
