Sudheesh Katkam updated CALCITE-823:
------------------------------------
Attachment: CALCITE-823-0.patch
Attached a patch. I also opened a [pull
request|https://github.com/apache/incubator-calcite/pull/128]. I am unable to
change the status of the JIRA to REVIEWABLE or assign the JIRA to myself.
I made 'ALTER scope' part optional so implementors can assume a default scope
(for Drill, we assume SESSION).
>From PostgreSQL, it looks like
>[RESET|http://www.postgresql.org/docs/8.4/static/sql-reset.html] (rather than
>UNSET) is available.
> Parser support to reset an option
