Just a quick note to say that I found a blog over the weekend with a number of interesting posts, so I thought I’d pass it on: http://www.bobbydurrettdba.com/

There’s a really cute example (complete with test case) of an optimizer bug (possibly only in 11.1)  in the December archive: http://www.bobbydurrettdba.com/2012/12/04/index-causes-poor-performance-in-query-that-doesnt-use-it/

  1. Jonathan,

    Thank you for mentioning my blog. I’ve learned a ton from your “Cost-Based Oracle Fundamentals” book and from your forum postings and blog. I appreciate your work.

    - Bobby
