--------------------------------------
Thank you all for helping.
> Calcite rejects valid query with multiple ORDER BY columns and constant RANGE
> bounds in window functions
> --------------------------------------------------------------------------------------------------------
>
> Key: CALCITE-5863
> URL: https://issues.apache.org/jira/browse/CALCITE-5863
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.34.0
> Reporter: Itiel Sadeh
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.36.0
>
>
> Usually, it is not valid to specify multiple ORDER BY columns with RANGE
> bounds in window functions:
> {code:java}
> SELECT sum(x) OVER (ORDER BY x,y RANGE BETWEEN 3 preceding and 4 following)
> from t;{code}
> However, it is valid if both bounds are "constant" bound (CURRENT ROW,
> UNBOUNDED PRECEDING and UNBOUNDED FOLLOWING), i.e:
> {code:java}
> SELECT sum(x) OVER (ORDER BY x,y RANGE BETWEEN UNBOUNDED PRECEDING and
> CURRENT ROW) from t;{code}
> (tested on PostgreSQL and SQL Server)
> Calcite will incorrectly reject it.
