Hi, I notice there are two PRs [1] and [2] working on this feature, one is for rel/0.12, and another is for master. However, their function definitions are different.
>From my side, I opt for PR 1, as it has the same syntax with other SQLs like MySQL. [1] https://github.com/apache/iotdb/pull/3738 [2] https://github.com/apache/iotdb/pull/3734 Best, ----------------------------------- Xiangdong Huang School of Software, Tsinghua University 黄向东 清华大学 软件学院
