Julian Hyde commented on CALCITE-2165:
--------------------------------------
Thanks for the test case. The problem is that {{getMonotonicity}} has
ascertained that the operand is constant, but not every constant expression is
a literal.
The javadoc of {{SqlOperatorBinding.getOperandLiteralValue}} says "If the
operand is not a literal, the value is null", so I think you should make all
implementations of that method do that. Hopefully that doesn't break anything.
> SqlCallingBinding.getOperandLiteralValue should ignore AssertionError
