Repeated bitwise negation
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The bitwise negation unary operator reverses itself, when called repeatedly, meaning that redundant BIT_NOT() operators can be removed.
Using Settings.transformPatternsBitNotBitNot, the following transformations can be achieved:
-- With Settings.transformPatternsNegNeg active, this: SELECT ~(~(x)), ~(~(~(x))) FROM tab; -- ... is transformed into the equivalent expression: SELECT x, -- ~(~(x)) ~x, -- ~(~(~(x))) FROM tab;
