Jeff,

You need to use the views. Each view will cause the queries to be fired off.

Views don't have access paths so creating them and not using them buys you nothing.

Subject: SQL VIEW

I have a complex SQL Select statement that builds 2 CTE's from a physical file using different selection criteria.
I have created separate SQL views for each of the selection conditions.
Do I need to specify the VIEW in my Select or will it use them under the covers.
I have not seen any messages in the log (run with DEBUG) indicating that the Views were used.
Will the use of Views with selection help shorten the time the statement takes?

I have an Index over the physical file with the keys that were recommended, and I do see that the Index is being used.

Thanks,

Jeff Young
