Column Group Catalog

Filed under: CBO,extended stats,Indexing,Oracle,Statistics — Jonathan Lewis @ 5:16 pm BST Sep 27,2018

I seem to have written a number of aricles about column groups – the rather special, and most useful, variant on extended stats. To make it as easy as possible to find the right article I’ve decided to produce a little catalogue (catalog) of all the relevant articles, with a little note about the topic each article covers. Some of the articles will link to others in the list, and there are a few items in the list from other blogs. There are also a few items which are the titles of drafts which have been hanging around for the last few years.
