May 4, 2021 at 7:03 comment added Netch A typical NULL can either denote "no data what value is real here" and "we know there is no value", among with a lot of more subtle variants (e.g. temporary or permanent absence of value). Having a unified NULL for both is the main reason why SQL NULLs are that messy and regularly confusing programmers.
