Also be aware that there's a gotcha when using WHERE abc NOT IN (SELECT
xyz FROM ...) that has bitten me a few times in the past...
Perhaps not an issue in this scenario because it's an ID and likely NOT
NULL, but if the select subquery ever returns a NULL value for xyz the
condition
Yikes looks so simple once the answer is here haha. I’ll check in the
morning if the Id is unique across the board. Thanks I appreciate the help.

If the ID is unique across all records,

Apologies if this is basic for probably most of you but I just can't get my
head around it.
I have a flat table in sql server which contains lots of duplicates,
differing only by one column.
Id,Name,Desc,Date,Etc
1,abc,abc abc,2022-11-17,a
2,abc,abc abc,2022-11-17,a
5,def,def def,2022-11-17,a
