-------------------------------------

[~danny0405]. I agree with your comment. Implicit type conversion would fix this issue, and I also think that it is a much better idea. I uploaded my PR with a simple test case. Do you mind adding that to your PR? Then, I think we could resolve this ticket along with CALCITE-2302.

> Range expressions like <ts> = 'literal' AND <ts> < 'literal' trigger ClassCastException as literal are implicitly casted differently between =/<> operators and other comparison operators. Apply the same casting rules for comparison to =/<> calls when processing ranges, so that all the terms have the same type for literals.
