1. On first Import (its XML but thats not important), fields are matched in the import, creating the entries (all with unique IDs).
2. Now I want to import again, this time the XML contains additional entries BUT also the entries from the first import (additional IDs).
3. How do I import only the additional entries without overwriting any records that are already in the DB?
Just give me some basic idea on how to accomplish this...
Thanks in advance
