Julian Hyde commented on CALCITE-4987:
--------------------------------------

[~yanjing.wang], I have removed 'fixVersion = 1.35.0' because the PR has conflicts. If you rebase the PR and remove the conflicts I will try to get it into the upcoming release.

> I reproduce with the following query.
>  
> {code:java}
> SELECT sum(shelf_width) as shelf_width FROM product ORDER BY shelf_width{code}
> you must have noticed that the shelf_width alias is same with field 'shelf_width' in sum.
> I expected the query hasn't changed when I test in RelToSqlConverterTest. But I get unexpected query is 
> {code:java}
> SELECT sum(shelf_width) as shelf_width FROM product ORDER BY sum(shelf_width)  {code}
>  the unexpected query is not valid in the dialect which support order by alias conformance.
