> Key: CALCITE-975
> URL: https://issues.apache.org/jira/browse/CALCITE-975
> Project: Calcite
> Issue Type: Bug
> Reporter: Jinfeng Ni
> Assignee: Jinfeng Ni
> Labels: drill
>
> This comes from a commit in Drill's forked Calcite.
> (https://github.com/dremio/calcite/commit/84bae715310d8684ac545f0a4f17c86d19e502a4)
> PlannerImpl.validate() only returns SqlNode after the input SqlNode goes
> through SqlValidator check, and it does not return the validated rowtype.
> This is different from the regular code path in CalcitePrepareImpl, where
> validate rowtype is passed into ParseResult/ConvertResult.
> We should provide a way in PlannerImpl such that the validated rowType is
> accessible.
