Matthias Pohl commented on FLINK-31105:
---------------------------------------

[~jingge] out of curiosity, where do you see the flaws in the approach allowing 
to omit the semicolon for the non-standard methods QUIT, HELP, EXIT? It 
wouldn't change anything in terms of using these methods with a semicolon. I'm 
not passionate to push that change forward. I'm just curious where you see the 
disadvantage of this being implemented.

[~Sergey Nuyanzin] has a point with the auto-completion. I agree to that 
proposal as well.

> SqlClient: Make HELP, EXIT and QUIT also work without a semicolon

> 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.
