[GitHub] [iotdb] Haze-Lan opened a new issue, #7434: 当时序不存在的时候能否直接返回空
Haze-Lan opened a new issue, #7434:
URL: https://github.com/apache/iotdb/issues/7434
IoTDB> select variable,number,save,value from root.product.1_data.57 where time >=1664146800000 and time <=1664153923031 and variable in ( 'Location') order by time asc
Msg: 411: Error occurred in query process: Unknown time series root.product.1_data.57.variable in `where clause`
因为设备未报数据过来所以 表内是没有数据的，如果要过滤某个值就会报错，这里能不能处理成跟time一样 没有值就返回为空

IMO, it is different between "no data" and "no schema".. Users may need to do some other action when they meet the latter case.
