Nicholas Jiang updated FLINK-21774:
-----------------------------------
Summary: Do not display column names when return set is emtpy in SQL Client
(was: Do not display column names when retrun set is emtpy in SQL Client)
> Do not display column names when return set is emtpy in SQL Client
> ------------------------------------------------------------------
>
> Key: FLINK-21774
> URL: https://issues.apache.org/jira/browse/FLINK-21774
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Client
> Reporter: Jark Wu
> Assignee: Nicholas Jiang
> Priority: Major
>
> Currently, SQL Client will display column names even if the return set is
> empty:
> {code}
> SHOW MODULES;
> +-------------+
> | module name |
> +-------------+
> 0 row in set
> !ok
> {code}
> In mature databases, e.g. MySQL, they only show "Empty Set" instead of column
> names:
> {code}
> mysql> show tables;
> Empty set (0.00 sec)
> {code}
> We can improve this by simply omit the column names header.
