Lorenzo Affetti commented on FLINK-34459:
-----------------------------------------

[~martijnvisser] well, if the name is a long one it can be truncated 
automatically via a simple check.

I like the proposal as it would increase the quality of result understanding (y)

> Results column names should match SELECT clause expression names

>                 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).
