NOT OR
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The NOT unary operator applied to OR 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 OR y = 2), NOT (x = 1 OR y = 2 OR z = 3) FROM tab; -- ... is transformed into the equivalent expression: SELECT NOT (x = 1) AND NOT (y = 2), NOT (x = 1) AND NOT (y = 2) AND NOT (z = 3) FROM tab;
