Hi,
Now I'm trying to design and develop a new 'last' function to get the last
time-value pairs in one or several timeseries, working on JIRA issue
[IOTDB-298], Now an example of this function is SELECT LAST(d0.s1, d1.s2) FROM
root.sg1 , to get the last value in root.sg1.d0.s1 and root.sg1.d1.s2
You can see the function's particular grammar and examples in the attached
file last.md .
I'm glad to get your suggestions. Thank you.
