Answer 1

I was looking for something like this for a many-to-many join situation where I want to show how many duplicates exist in both tables. count(distinct col) wasn't exactly the right solution because result of '1' indicated that the column indeed had duplicates, but didn't say how many. The 'opposite of distinct' I used for this was an inversion using count(*): (count(*)-count(distinct col)+1) and it did the job fine.
