NOT AND

Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition

The NOT unary operator applied to AND can be distributed applying De Morgan's law.

Using Settings.transformPatternsNotAnd, the following transformations can be achieved:

-- With Settings.transformPatternsNotAnd active, this:
SELECT
  NOT (x = 1 AND y = 2),
  NOT (x = 1 AND y = 2 AND z = 3)
FROM tab;

-- ... is transformed into the equivalent expression:
SELECT
  NOT (x = 1) OR NOT (y = 2),
  NOT (x = 1) OR NOT (y = 2) OR NOT (z = 3)
FROM tab;
