Alistair:
Thanks. I got this answer fro AskTome site and is trying now. But according to the example from Tom, I will end up with duplicated rows of records. For example, After i export the data out of the table, I removed some of data before a certain date and let the table keep growing with new ones. So when I import again, I will have some overlap data ( from when I export to that date ). I am looking a solution to remove one of the duplicated ones and keep only one left. Have any suggestions? appreciate again.
