I started with blogging about COUNT = 0 situation. Then I followed it with COUNT = 1. So, let’s do a COUNT = 2 today. No, no, I am just kidding, don’t worry 🙂 But I still have to do one more COUNT post, one that will cover all other COUNT situations.

It may be 0, 1 or 75 or whatever, but you need to know exactly how many. These situations are few and far between, but every once in a long while this is what you need.
So, let’s give the COUNT function one last kick from another angle.
