Normalise fields compared to values
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
When comparing column expressions with values, the various pattern replacements profit from a simplification where we normalise the order of operands to have the value on the right side of the operator.
Using Settings.transformPatternsNormaliseFieldCompareValue, the following transformations can be achieved:
-- With Settings.transformPatternsNormaliseFieldCompareValue active, this: SELECT * FROM tab WHERE 1 = a; -- ... is transformed into the equivalent expression: SELECT * FROM tab WHERE a = 1;
