@pavanvora Flux will return each field in separate tables because InfluxDB returns data group by series, and the field key is part of the series key. There are a few ways you can do accomplish what you’re trying to do that are outlined in this similar thread: [InfluxQL to new task FLUX with resample and group](https://community.influxdata.com/t/influxql-to-new-task-flux-with-resample-and-group/18266)
