Hi, I'm prepared to add a new feature in IoTDB as follows:
Currently, when doing a query like *`select s1 from root.sg.d1`*, the result shows like: | Time | root.sg.d1.s1| | ... | ... | The column name *includes all prefix paths which are complex* and seem inflexible and inconvenient in some situations. Therefore, I think we can add a new feature by adding the alias of time series, which is like a relational database. For example, *`select s1 as d1_temperature form root.sg.d1`* The result will be like: | Time | d1_temperature | | ... | .... | However, the new feature may be *limited* in IoTDB as a time series database. Because it's not matching one time series for one suffix path exactly in SELECT Clause. For example, `select s1 as temperature from root.sg`. If two devices d1 and d2 exist in root.sg, then they can't both be temperature. We have to throw an exception here. So we have to request that *every alias input by users is matching one time series exactly.* Any suggestions or questions are welcome! Thank you! -- Best, Xiangwei Wei
