Doing my morning article "skimming" and saw this one. In the "Conclusion" it's stated "This way I avoid using a GROUP BY "... and the example right above it has two CTE's... and each has a GROUP BY in it. I admit that's it's just a "skim" so far (I'll read it in depth tonight), but just exactly what do you mean by you avoided the use of GROUP BY?
