Welcome to my Oracle blog and here are the Posts.
I do not blog on a regular basis. Only when I find something interesting to say that doesn’t seem to be available elsewhere. So if you are interested in what I have to say why not set up an RSS feed or use the “Follow” button on the right?
You will see pages on the right that provide links to my published articles, contact details and so on.

By the way: the reason the example that performs aggregates using analytic functions runs so slowly is (as I suspected) because of the unused columns. Replace ‘*’ with a smaller number of columns and it runs like a champ!
