I have a table Order . I need to load data into another table OrderDuplicates based on a select criteria where there are more than one occurrence of the following two column grouping, OrderID, OrderNumber.
Order and OrderDuplicates have same structure

Order
---------
OrderID
OrderNumber
OrderDate
OrderPrice
OrderUserid

So if I have the foll data
OrderID     OrderNumber    OrderDate            OrderPrice      OrderUserid
1                21                      09/01/2008             10.00           abc
1                21                      09/02/2008             12.00            lmn
1                21                       09/03/2008             11.00           xyz
1               20                       09/01/2008                10.00m       abc
2               19                       09/01/2008               9.00            xyz
2               19                       09/02/2008               10.00            abc
3               13                      09/02/2008               10.00             xyz
5               12                      09/03/2008               11.00            abc
6               12                       09/01/2008              10.00             xyz
6               12                       09/03/2008               9.00                abx

I would want the foll rows loaded into OrderDuplicates
1                21                      09/01/2008             10.00           abc
1                21                      09/02/2008             12.00            lmn
1                21                       09/03/2008             11.00           xyz
2               19                       09/01/2008               9.00            xyz
2               19                       09/02/2008               10.00            abc
6               12                       09/01/2008              10.00             xyz
6               12                       09/03/2008               9.00                abx
