Would it make sense to bring some of this into Calcite's documentation?
Perhaps a website update or a Maven module which shows how this can be
done with a specific version of Calcite (preventing documentation-rot)?
Before I end up volunteering myself, it would certainly be a good
exercise to look at how both Drill and Phoenix do these DDL extensions
now :)

SELECT and DML are standardized, but DDL tends to be database-specific, so our policy
is that you make DDL extensions outside of Calcite. See
https://issues.apache.org/jira/browse/CALCITE-609<https://issues.apache.org/jira/browse/CALCITE-609>
for example. You should be able to copy work that has already been done in Drill
and Phoenix in extending Calcite’s core parser for DDL.

主题: Re: [QUESTION] Does Calcite support parsing DDL like CREATE TABLE ?
does this mean I have to do the lexical parsing as well as semantic parsing all
by myself if I want this functionality?

you must parser DDL and register the stream or table schema to calcite
by using calcite API.

主题: [QUESTION] Does Calcite support parsing DDL like CREATE TABLE ?
Hi,
I want to use calcite to parse some DDL statements like “CREATE
TABLE”, “CREATE FUNCTION”, “INSERT TABLE” and so on. I tried to use
PlannerImpl to parse the DDL statement, but it throws exception that
do not know “CREATE”.
So my question is that does Calcite support parsing DDL? If not ,
how can I support it myself?
