Yes yes, all fine and good. I love SQL, think it is incredible how relevant it still is as a high level language, and think it should be the basis of almost every data storage and retrieval system out there. And I love that the foundation is relational algebra, which is an extremely useful abstraction for data management.

But for the love of god, get rid of the ternary logic. It is only mathematically sound to the extent that mathematicians are masochists and will try to formalize anything regardless of how painful it is for normies. Boolean logic is good enough and doesn't feel like an exercise in retroactive continuity.
