Ah yes, someone discovering the existence of three value logic in SQL and expecting 2VL behavior. Classic. We've all been there, right? Personally I wish more languages were like python or ruby and had chosen None or Nil over Null which alleviates the confusion a bit, as those names better indicates that it's NOT an "unknown" (1 unknown value != 1 other unknown, which intuitively makes sense.) In ruby or python it's more obvious that None and Nil are "nothing" types and therefore equivalence makes sense (nil == nil, None == None are both true) |
