             Summary: TUMBLE TVF should throw helpful exception when specifying second interval parameter
                 Key: FLINK-22523
                 URL: https://issues.apache.org/jira/browse/FLINK-22523
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Planner
            Reporter: Jark Wu
             Fix For: 1.14.0, 1.13.1


Currently, the following query can run and no exception is thrown. 

However, the second interval parameter (i.e. the offset parameter) is not supported yet. We should throw a exception for this. 


{code:sql}
select 
  date_format(window_end, 'yyyy-MM-dd') as date_str,
  date_format(window_end, 'HH:mm') as time_str,
  count(distinct user_id) as uv
from table(tumble(table user_behavior, descriptor(ts), interval '10' minute, interval '1' day))
group by window_start, window_end;
{code}
