Julian Hyde commented on CALCITE-2721:
--------------------------------------
Yes, that is what I am referring to. At this point, all we should do is the
parser (i.e. add a test to SqlParserTest and make it pass). Validation and
execution could be done later.
The parser cannot distinguish between {{mySchema.mySubSchema.myFunction()}} and
{{myTable.myColumn.myField.myMethod()}} (because it does not resolve names) so
the parse tree for both of these examples would look similar.
When implementing this, make sure you don't conflict with CALCITE-2674, which
has a PR almost ready to commit.
