Hi Timo, Thanks.
yes. We need to make Flink's implementation of this feature more scalable
and versatile.
I will try to update this FLIP on the comparison and difference of the
implementation of some features
on other popular or commercial engines you mentioned.
Let us see how to find a better
Hi Ran,
adding additional filter and selection capabilities makes sense.
However, I would recommend to not only check Spark or Hive but also
focus on bigger commercial players such as Snowflake, Oracle, SQL Server.
In any case, maybe we should also investigate more thoughts on a Flink
Hi Ran,
When you're creating your FLIP, please also have a look at Calcite SQL
parser, since that's used by Flink [1]

Yes, I totally agree with your point. The current flink sql syntax is tiled
together without classification.
Let me try to summarize these four categories, not just Auxiliary
Statements. And compare it with other popular engines.
Thank you, Jing !

+ 1 for a new FLIP
It would be great if we could take this opportunity to go through all
current Flink SQL syntax and define a feasible classification in the FLIP.
In my opinion, the 4 categories, i.e. DDL, DML, DQL, DAL , used in Spark
doc [1] make sense.
We will then have a better big picture
Thanks. I will create a FLIP to illustrate some details.

Thank you,
I think this is worth a FLIP design doc to discuss the detailed syntax.
Could you prepare a FLIP for that?

Hi Ran,
I think it’s always nice to support new syntax if it’s useful for the users.
From my side, your syntax table is broken. Could you share it with a Google doc
or create a JIRA issue?

Hi guys. When I recently used flink sql to manage internal metadata
(catalog/databases/table/functions),
I found that many current flink sql statements do not support filtering or
some advanced syntax, however these abilities are very useful to end-users.
These are some statements I have
