SQL Syntax: How to Find Commonality Among Similar Results

Hello:

Below is my code.  After it is a screenshot.

I want only rows 10 - 18.  As you can see, the difference between these rows and the others is that you have more than one "DocumentNumber".  Yet, you have only one "APTODCNM".

Specifically, for rows 10 - 18, I want the "Cnt" value to say 1, and the other rows to say "0".

I mean no offense, by this next request.  But, I don't want to hear anybody ask for sample data.  

This is a simple SQL syntax question.  That's all.  No background is required.  I know that you solid SQL coding gurus out there can solve this in your sleep.  Perhaps, it's simply a matter of adjusting the "HAVING...COUNT" syntax at the end of my query.

I look forward to hearing back on this, when I arrive in the office tomorrow.

Have a great night!

John

Specifically, for rows 10 - 18, I want the "Cnt" value to say 1, and the other rows to say "0".

so you can have this for your "cnt" field:
case when COUNT(*) OVER (PARTITION BY RM20201.APTODCNM) > 1 then 1 else 0 end AS Cnt

Try COUNT(*) OVER (PARTITION BY RM20201.APTODCNM) AS Cnt instead of your cnt
