TUMBLE TVF should throw helpful exception when specifying second interval parameter

    XMLWordPrintableJSON

    Details

      Description

      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.

      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;
