Hey this is nice one time work at startup. Few of more questions

- I will have to remake the RV to use connections instead of ODBC DSN
- The same connection is common for all the RV's in the DBC
- Change the connection settings, if and when required, and all the RV's in the DBC are up to speed onto this new ODBC DSN as named in the connection
