+1 for online meetup.
And I’m curious about if there is any playback for this meetup, because
somebody might couldn't attend due to timezone variety or any other reasons.

As far as I can tell, Calcite doesn’t provide a simple way to get table names
or column names for a query(or maybe I miss something).
But you can take a look at SqlSelect、SqlOrderBy and SqlWith if you want to do
such things. Based on my own experience, SqlVisitor seems the only way t
