That's great except for when you're interacting with a decrepit data system from 10 years ago with a variable record format.

Some things can't be locked in stone, and SQL will leave you out to dry when that's the case.

I use graph database, and resources of the graph are typed with types/supertypes. Relationships also are typed with types/supertypes. And my queries are heavily dependant on that typing structure.

Honestly, I cannot live without that feature. [sorry, that is my OOP minute. Continue without me...]
