My RV, they have to have tables selected from. Currently I select them directly from the ODBC DSN names. I am lost. If I use ODBC DSN name as I currently do, 2 copies of my app installed on the same computer in different folders and both of them started at the same time will start using each others data (atleast of the copy started last).

So in you example I am assuming the RV has been based on the connection named 'C09_VSO3Data_FB' and I have 2 different ODBC DSN created namely 'C09_VSO3Data_FB_12345' and another for eg. 'C09_VSO3Data_FB_67890'.

If so this is pretty near to what I want. Then comes the question where/when can I execute the above command? Will it be enough to execute this command once at the time the appliaction has been install and run for the first time?

Sorry about being a slow learner.
