Day 95/365 | Handle NULL Values Using NULLIF | English

Lawyers. Ignoring definitions of words like nullify, nullification, and null from dictionaries of both the 18th century and today, most lawyers claim the only definition of nullification is the legal one. They're wrong. In the end, if the states continue pushing back, and the feds back down, the lawyers can call it whatever they want, and we’ll call it what it is - nullification. #nullify #nullification #liberty #10thAmendment #constitution #history #freedom | Tenth Amendment Center
