EXCEPT returns any distinct values from the left query that are not also found on the right query. The key to this is of course the use of DISTINCT.

DISTINCT was clearly the key here. Thanks for this basic question. :-)

Easy enough if you know how EXCEPT and related options work.

But don't quite understand the statement "The key to this is of course the use of DISTINCT".
There is no use of DISTINCT, so how can it be the key to anything?

First sentence of the explanation, emphasis mine:
"EXCEPT returns any distinct values from the left query that are not also found on the right query"

I guess you're right. I'd assumed it meant the keyword DISTINCT, given that it was in uppercase Smile

Thanks for the question. It might be easy for others, however I learnt something on this. I did not do my research first and thought it would be three.


Same here.
