Julian Hyde commented on CALCITE-1168:
--------------------------------------
I don't think we should use MySQL as a model. They are not very good at reading
the SQL standard before they implement features.
And in fact recent versions of the standard have "DESCRIBE query". I don't want
to clash with that.
I propose that we keep EXPLAIN as is, but add DESCRIBE SCHEMA name, DESCRIBE
TABLE name, DESCRIBE query.
> Extend EXPLAIN statement
