You can see this in some execution plans that access a partitioned table through a local index when some of the index partitions have been marked unusable.
Oracle is able to generate one plan for the partitions where the index partitions are usable and another where the index partitions are unusable.

Thanks for that.

Thank you for the warning. When I downloaded the presentation at home after a simple google search there was no problem; but the file is on the web pages of the Slovenian Oracle User Group, and I guess the google cache in my home machine must have the id/password from the time I presented at their annual conference.

I have seen a note on Julian Dyke’s blog that it might be available as one of the OOW 2010 presentations for people who have access to those downloads.

1) The distinct aggregate transform view can shown as VW_DAG_n (I have not seen DAT used myself)
2) Table expansion transformation is shown as VW_TE_n
