I am writing cf mobile app and using cfclient tag. I am encountering issue with remote datasource connection and can’t get it resolve. From cfclient I am using “rooms” as my datasource string which is defined in administrator as data source. It is connecting to remote sql server. “Tblblogs” exist in rooms database, but under cfclient i get error that “No such table exist”. However, if I take same query [blgQ] that selects “tblblogs” outside cfclient, it works fine without issue. I am not sure why it is not making right datasource connection under cfclient (as defined in administrator) <html>
