OK - I'm fine with the idea that there can be more than one name for the
same thing, and that different geographies and/or cultures can mean that
people use synonyms.


I've recently started looking at Oracle as well - boy oh boy, you'd want

OK, fine. Can you show me an example of where your construct (inline
view and/or derived table) behaves differently from and is better than
the syntax that I used?
