------------------------------------
[~danny0405] Absolutely. Feel free :-)
> Record DOT extension does not distinguish between simple and compound

> Key: CALCITE-2906
> URL: https://issues.apache.org/jira/browse/CALCITE-2906
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Rong Rong
> Priority: Major
>
> Currently the DOT extensions only supports Simple Identifiers:
> For example:
> * *{{tbl.foo(0).col.bar}}* is parsed as: *{{((`TBL`.`FOO`(0).`COL`).`BAR`)}}*
> However, this is not the case in regular Expression field, for example:
> * *{{tbl.col.bar}}* is parsed as: *{{`TBL`.`COL`.`BAR`}}*
> Parser should support both compound identifier, and simple identifier chain
> after a record type SqlNode.
