             Summary: PlannerImpl.validate() should return validated row type
                 Key: CALCITE-975
                 URL: https://issues.apache.org/jira/browse/CALCITE-975
             Project: Calcite
          Issue Type: Bug
            Reporter: Jinfeng Ni
            Assignee: Jinfeng Ni


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.
