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

     [ https://issues.apache.org/jira/browse/CALCITE-800?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Julian Hyde resolved CALCITE-800.
---------------------------------
       Resolution: Fixed
    Fix Version/s: 1.4.0-incubating

Fixed in http://git-wip-us.apache.org/repos/asf/incubator-calcite/commit/ef5833f3. (I don't mean the discussion is over -- although I hope it is :) -- but the original issue, namely the validation of window functions, is fixed.) Thanks for the patch, [~seanhychu]!

> For instance,

> select sum(deptno) over (order by 
> sum(deptno) over(order by deptno)) 
> from emp
> {code}
> This is an invalid query. However, it passes the validation.
