[jira] [Commented] (CALCITE-2542) SqlNode AtomicRowExpression + DOT operation does not work for constructed ROWs

["Julian Hyde (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CALCITE-2542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16706419#comment-16706419 ] 

Julian Hyde commented on CALCITE-2542:
--------------------------------------

I reviewed, and it makes sense to check for "*" (e.g. tableName.columnName.*.field) at validation time rather than parse time.

Fixed in [45258404|http://git-wip-us.apache.org/repos/asf/calcite/commit/45258404]; thanks for the PR, [~walterddr]!

> 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}
