Using Settings.transformPatternsMergeAndComparison, the following transformations can be achieved:
-- With Settings.transformPatternsMergeAndComparison active, this: SELECT x = a AND x >= a, x = a AND x <= a, x > a AND x < a, x > a AND x != a, x < a AND x != a -- And many more FROM tab; -- ... is transformed into the equivalent expression: SELECT x = a, -- x = a AND x >= a, x = a, -- x = a AND x <= a, x != x, -- x > a AND x < a, x > a, -- x > a AND x != a, x < a -- x < a AND x != a -- And many more FROM tab;
