Re: Response Time Problem using Oracle ODBC links to Access Database

I would start by running the queries in the Oracle SQL Plus, then see what the response time is...

If you are using Access functions as part of your query, then you cannot do this. You could try copying everythign to a local table every so often, but that is kind of clunky...
