----------------------------------------
Yes that makes sense. Sure thing
> Results column names should match SELECT clause expression names

> Key: FLINK-34459
> URL: https://issues.apache.org/jira/browse/FLINK-34459
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Client
> Affects Versions: 1.18.1
> Reporter: Jeyhun Karimov
> Priority: Minor
>
> When printing {{SQL SELECT}} results, Flink will output generated expression
> name when the expression is not {{column reference or used with alias/over.}}
> For example, select a, a + 1 from T would result in
> {code:java}
> +----+-------------+-------------+
> | op | a | EXPR$1 |
> +----+-------------+-------------+
> | +I | 1 | 2 |
> | +I | 1 | 2 |
> | +I | 1 | 2 |
> +----+-------------+-------------+
> {code}
> Instead of the generated {{EXPR$1}} it would be nice to have {{a + 1}} (which
> is the case in some other data processing systems like Spark).
