Usually the connection to Oracle 11G requires that you use the Oracle ODBC driver. We use the Mircrosoft ODBC driver by default. I assume you have an Oracle client installed? If so go to your Oracle connection properties and on the advanced tab choose the Oracle ODBC driver from the drop down and retry. Use a new Query builder and buidl the query again.
