KrishnaKant Agrawal commented on CALCITE-2625:
----------------------------------------------
{quote} In SqlImplementor.Context.toSql(RexProgram program, RexOver rexOver),
look at sqlAggregateFunction.allowsFraming() and wipe out the upper and lower
bound if framing is not allowed.{quote}
This makes sense. Will update SqlImplementor.Context.toSql(RexProgram program,
RexOver rexOver) to not pass Bounds to SqlWindow if
sqlAggregateFunction.allowsFraming() is false
> ROW_NUMBER, RANK generating Invalid SQL

> Key: CALCITE-2625
> URL: https://issues.apache.org/jira/browse/CALCITE-2625
> Project: Calcite
> Issue Type: Bug
> Components: jdbc-adapter
> Reporter: KrishnaKant Agrawal
> Assignee: Julian Hyde
> Priority: Major
>
> The SQL standard says:-
> If <ntile function>, <lead or lag function>, <rank function type> or
> ROW_NUMBER is specified, then: … The window framing clause of WDX shall not
> be present.
> So, Calcite should not print the Window Frames when such functions are used.
