>                 URL: https://issues.apache.org/jira/browse/CALCITE-5656
>             Project: Calcite
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 1.34.0
>            Reporter: luoping.zhang
>            Priority: Critical

>  For example:
> Query SQL is 
> {code:java}
>  select a from table order by coalesce(a,b){code}
> When we convert this sql to relNode and convert it back to SQL by RelToConverter, the result is:
> {code:java}
> select a from table order by 2{code}
> But this sql syntax is wrong because there is no ordinal 2
