Does anyone know where I can find extensive info/examples of this? I've checked all my Oracle books and MetaLink with negative results. My project is employing this scheme, but I do not yet have the DDL for it available to me. I would like to better familiarize myself with it. All I do know is what's described in the Oracle Press 24x7 book, Chapter 6, top of page 259. The scheme is used to routinely purge old partitions and roll in new ones for partitioning based on windows of inclusive dates. Thanx for any help you can give me on this!
