> The method relies on {{RexUtil.predicateConstants}} which in turn calls {{RexUtil.canAssignFrom}}. {{RexUtil.canAssignFrom}} is skipping any check on precision and scale. I observed the error in Hive when two VARCHAR types with different precision were given to the method, which was resulting on considering the result of the narrowing cast as the value of the reference. This lead to incorrect results.
