I don't have 8.5 here, but go under More Data Sources (something like that) and select additional data sources, point to your ODBC connection and say add.
It will prompt and allow you to paste in SQL which is passed to the database. An often overlooked means to buidl a quick ad hoc report in CR 8.5 from existing or custom SQL.
CR 9 handles this better, but CR 8.5 does it too.
