You should normalize the parseNode too. This puts constants on the RHS as
expected among other things. You can do this like this:
parseNode = StatementNormalizer.normalize(parseNode, resolver);
A good test is to use a constant on the RHS and it'll be moved to the LHS
(like in a CASE WHEN statement).
