You need to setup a data source in the ColdFusion administrator. The connectstring attribute was removed starting with CF 6. If you are trying to specify an "Appliation Name" as part of a connection string you might try specifying that information in the advanced data source settings.
Thank you. Can the session vars be accessed from the advanced data source settings?
I'd like to pass the #session.clientid# var in the connection string with the app name (which is why I was hoping to use the connectstring attribute in the cfquery tag -- to overwrite the dsn info)
I'm trying to determine who is logged on to the app when certain queries are run, and that is how to access that info - #session.clientid#
