> Method {{accept}} is used to make sure the SQL operator is supported in Beam SQL. IMO it should only check the case that some scenarios are not supported in BeamSQL even it's valid in Calcite SQL grammar.
> It's not necessary to my understand to validate SQL grammar as that's done already in the parsing phase.
