Massive Delete

The question of how to delete 25 million rows from a table of one billion came up on the ODC database forum recently. With changes in the numbers of rows involved it’s a question that keeps coming back and I wrote a short series for AllthingsOracle a couple of years ago that discusses the issue. This is note is just a catalogue of links to the articles:

There is an error in part 2 in the closing paragraphs – it says that the number of index entries deleted varies “from just one to 266″, it actually varies from 181 to 266.
