Re: Partitioned view question

Have you set the init.ora parameter:

    partition_views_enabled=true ?

Have you analyzed the table so that the optimizer realises they are large enough to make the overhead of partition elimination worthwhile ?

If this doesn't help, then there is a document on my website that might be worth a quick look.
