The Druid window function is used without a group and returns nothing. If the function has to use group by, throw an exception when it is not there ### Affected Version latest 29.0.1 ### Description The Druid window function is used without a group and returns nothing. If the function has to use group by, throw an exception or report a syntax error when it is not there. 1. select a from tb -- working and showing 10 rows for example 2. select a, row_number() over() as rn from tb -- working but shows nothing and no exceptions or errors 3. select a, row_number() over() as rn from tb group by a -- working fine with proper row number For case 2, please throw a syntax error instead of returning an empty result. I have tested both in Druid web UI and rest API. -- This is an automated message from the Apache Git Service.
