> When specifying window frame without an ORDER BY clause, Calcite will ignore it and will generate the frame UNBOUNDED PRECEDING to UNBOUNDED FOLLOWING. e.g, calcite will translate 
> {code:java}
> SELECT sum(x) over(partition by y ROWS between CURRENT ROW and UNBOUNDED FOLLOWING) from t
> {code}
> into 
> {code:java}
> SELECT sum(x) over(partition by y RANGE between UNBOUNDED FOLLOWING and UNBOUNDED FOLLOWING) from t
> {code}
> There is a comment in the offending code (SqlToRelConverter.java:2207) which states that 
> ??"without ORDER BY, there must be no bracketing"?? . I've tried to find a specification like that in the SQL 2003 standard, but didn't find anything to that effect.
