-----------------------------------------------------------------
Thanks both for the quick responses! I have updated the issue subject and body
as requested.
Re. "calling the parser and sql-to-rel-converter by hand", could you elaborate
on this? I've updated the issue description above to include the code I'm using
to call the parser and converter, is there a different recommended way?
Thanks for the attempted repro, I wonder if the issue has something to do with
a subquery in the from clause - maybe the below query might repro the
issue?{{{{}}{}}}
{{SELECT "dim4" AS "dim7", LEAD(COUNT( * ), -1) OVER (ORDER BY "dim4") AS
"measure10"}}
{{FROM (}}
{{ SELECT "deptno" AS "dim4" FROM emp) AS "t0"}}
{{GROUP BY "dim4"}}

> Hello all, I believe I have found a bug in SqlToRelConverter. The symptom and
> repro are outlined below, and the full stacktrace is attached. This is on
> calcite version 1.35.0. Any insight would be much appreciated, thanks!
> When I parse the below SQL string to get a SqlNode, and call
> SqlToRelConverter.convertQuery on this SqlNode, I get error:
> {quote}UnsupportedOperationException: class
> org.apache.calcite.sql.SqlBasicCall: LEAD(COUNT( * )) OVER (ORDER BY `dim4`)
> {quote}
> SQL:
> {{SELECT "dim4" AS "dim7", LEAD(COUNT( * ), -1) OVER (ORDER BY "dim4") AS
> "measure10"}}
> {{FROM (}}
> {{ SELECT "timestamp" AS "dim4" FROM "Shared.factDataset") AS "t0"}}
> {{GROUP BY "dim4"}}
> I have confirmed that my SqlToRelConverter instance seems generally ok,
> because it is able to convert many other SqlNodes to RelNodes. After some
> experimentation, I noticed that just changing `ORDER BY "dim4"` to `ORDER BY
> "t0"."dim4"` fixes the issue - after that, the SqlNode successfully is
> translated to a RelNode.
>
> Below is the way I am invoking convertQuery. The error comes in the last
> line, on invocation of convertQuery
> {{var config = Frameworks.newConfigBuilder()}}
> {{ .operatorTable(getOperatorTable())}}
> {{ .parserConfig(defaultParserConfig().build())}}
