I disagree - no surprise maybe - The problem you described seems to have been caused by taking what you say is your experience with Books Online  and doing what you would do to find something new in that structure namely going to the alphabetical index of all topics and scrolling through till you find the right thing. I can't find this alphabetical list of all topics though - there is a glossary at but common table expression isn't there, I assume there is some other index you had in mind. Books Online does have a pretty good tree structure arranging documentation by functional area, but then the homepage link you were referred to has a tabbed structure, errm arranging documentation by functional area (and online search and so on as well), but I'd imagine there is a reason you neglected to point out that Oracle makes the same class of navigation available in a different way.

Finally try subquery factoring clause - having looked up Common Table Expression on a Famous web search engine I discovered what on earth you were looking for - why you didn't start with the sql reference manual is beyond me.
