Hi,
I want to concatenate 2 qvds with intersected data.
I have 2 qvds. Both contain same field.
In qvd1, There is data that is only according to created date .
But In Qvd2 , There is data according to change date.
there is a key that is commom in both table.
I want to fetch only data from qvd1 that do not exist in qvd2 according to the key.
All data in qvd1 are not changed , So qvd2 contain only little data.
