---------------------------------------
Hi [~jfhannel], thanks for filing this case! Would you mind updating the title
to be a bit more specific/descriptive? Also if you want to format something as
code you can either surround it with {{ or use {code:java} (and close with }}
or {code})
> Possible bug found in SqlToRelConverter
> ---------------------------------------

> Key: CALCITE-6023
> URL: https://issues.apache.org/jira/browse/CALCITE-6023
> Project: Calcite
> Issue Type: Bug

> 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:
> ```
> UnsupportedOperationException: class org.apache.calcite.sql.SqlBasicCall:
> LEAD(COUNT(*)) OVER (ORDER BY `dim4`)
> ```
> 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.
