Hi All.
I am losing my mind over this little problem that I am trying to work out.
I have a SQL DB table which looks like this:

I am trying to create a gallery to list out the NCID which meet the following criteria:
a. EMAILSTATUS = NO
b. PONO are the same as other records
In effect, show the duplicated PONO.
I have found lots of info on DISTINCT, etc, but unable to find a post showing how to actually show duplicated records in a SQL db.
Any advice/hints would be greatly appreciated.
