Jialin Qiao commented on IOTDB-394:
-----------------------------------
Hi, currently you could use aggregations to get the results.
For example, getting the last time-value of root.sg1.d1.s1:
select last_value(s1),max_time(s1) from root.sg1.d1
The result is like this:
last_value(s1), max_time(s1)
1, 1
We plan to offer a new grammar like "select last(s1) from root.sg1.d1", the
result is:
path, time, value
root.sg1.d1.s1, 1, 1

> For example, if I have a device with 10 sensors (normal/abnormal detection
> status), I want to know the status of all the current sensors of this device,
> so I need to query the latest data point of all the sensors
