Julian Hyde commented on CALCITE-5724:
--------------------------------------
Or, rather than applying the planner rule, just ignore literals when generating
the {{ORDER BY}} clause. If {{ORDER BY}} is empty, skip it (but be sure to
generate {{LIMIT}} or {{OFFSET}} if applicable).
> Generated SQL uses literal values in ORDER BY clauses

> Key: CALCITE-5724
> URL: https://issues.apache.org/jira/browse/CALCITE-5724
> Project: Calcite
> Issue Type: Bug
> Reporter: Joey Moore
> Assignee: Joey Moore
> Priority: Major
>
> Current behavior in the SqlImplementor will generate SqlCharStringLiterals in
> ORDER BY fields when there is a Literal value in the SELECT clause. This
> happens in languages with isSortByOrdinal(). This leads to errors in dialects
> in which cannot have literal values in ORDER BY clauses such as BigQuery.
> Proposed fix is to use ordinals in all cases where a literal value is present
> in the SELECT clause.
> Example of current implementation:
> {code:java}
> select 3.14159265 as pi
> from \"product\"
> order by 1;
> {code}
> Will return
> {code:java}
> SELECT 3.14159265 AS \"PI\"
> FROM \"foodmart\".\"product\"
> ORDER BY '3.14159265'{code}
> Proposed implementation will return :
> {code:java}
> SELECT 3.14159265 AS \"PI\"
> FROM \"foodmart\".\"product\"
> ORDER BY 1{code}
