Jing Ge commented on FLINK-31105:
---------------------------------
Afaik, semicolon is quite convenience since we can write multiple lines command
and finish it with one semicolon. Some coding guidelines even make it explicit
that semicolon is mandatory and the semicolon must be written in the separate
line to improve the readability.
> SqlClient: Make HELP, EXIT and QUIT also work without a semicolon
> -----------------------------------------------------------------
>
> Key: FLINK-31105
> URL: https://issues.apache.org/jira/browse/FLINK-31105
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Client
> Affects Versions: 1.17.0, 1.16.1
> Reporter: Matthias Pohl
> Priority: Minor
> Labels: starter
>
> The special commands {{HELP}}, {{EXIT}}, and {{QUIT}} are not really part of
> the SQL syntax but rather tool-specific commands. Having the requirement to
> have the semicolon follow-up on these commands might not be necessary.
