I faced a problem when using Northwind sample Database. On of the table in the database is 'Order Details'. I am unable to query on the table because of the space in the name ('Order' 'Details') of the table. When I remove the space in the name, the reports associated in Cognos are not working properly. Let me know whether there is any purpose to put the name like that and if I want to see the data in query mode how it is possible.
