I use SQLStringConnect() function. You do not have to have a DSN or a DBC Connection.

sqlstringconnect('Driver=Microsoft ODBC for Oracle;UID=myid;PWD=mypwd;CONNECTSTRING=reg6;')

I believe only the Oracle drivers use CONNECTSTRING parameter. The rest use the SERVER parameter. You can get the descriptive name of the driver from the ODBC Admin in Control Panel.
