How to create a command (union) from 2 databases ( ODBC connection)?
I have my sql in a command and it works fine.  I do not see how to add a union from another database that is accessed through a seperate ODBC connection

Answer : How to create a command (union) from 2 databases?

I don't think you will be able to union the databases in the same command unless there is an actual link in between the databases themselves which you have indicated is not possible.
I think you should be able to add both databases as different datasources to the same report though and create another command for the second database. The report might complain that there are 2 start points for the data but it will still work.
