----------------------------------------------------------------
[~julianhyde], I've updated the PR to change the parser to parse subfield as
SqlIdentifier, and added a test to make sure that referring to an unknown field
gives an error in SqlValidatorTest. Can you take another look at the
PR([https://github.com/apache/calcite/pull/557])? Thanks.
