What expression mirrors NOT BETWEEN?

Question

Accepted Answer

NOT BETWEEN x AND y negates the inclusive range, producing col < x OR col > y. Because BETWEEN includes boundaries, NOT BETWEEN excludes them - a value of exactly 10 or exactly 20 does not pass. The AND option (col < 10 AND col > 20) is a logical impossibility; no single value can be simultaneously below 10 and above 20.
