-------------------------------------------------------------
This might have been similar to CALCITE-2016, I actually tried to modify the
{{Parser.jj}} to allow generically a {{<DOT>}} operator afterwards. Seems like
it also breaks some validation test which the SQL are suppose to be invalid.
For example:
{code}
SELECT emp.*^.^xx FROM table
{code}
should not be allowed.

> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Rong Rong
> Assignee: Julian Hyde
> Priority: Major
>
> It seems like some of the {{AtomicRowExpression}} (such as
> {{NamedFunctionCall}}) or rowSpan with {{<ROW>}} operator does not allow
> following DOT operators in Parser.jj
> To named a few, the following does not parse correctly.
> {code}
> SELECT ROW(col1, col2, col3).col1 FROM t
> SELECT myFunc(arg1, arg2).col1 FROM t
> {code}
