That "improved SQL" was already defined in the previous century, and has been implemented as well. Your ignorance drips off of every word you write.

- chris_wot 8y agoE.F. Codd literally designed null into the relational model. I don't think calling someone ignorant is very helpful.
- ErwinSmout 8y agoBut the demeaning ridicule that gets thrown at me is ? (BTW I doubt very much that "Codd designed null into the RM". Even his 12 rules mention only "a systemic way to deal with missing information", not "null".)
