> 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.
