Hi everyone.
I have a db that contains the following:
time, Status (“ready”,“running”,“stopped”), Address(“a1”,“a2”…)
So to get the latest status of each address and to filter it I did the following:
SELECT “last” FROM
(
SELECT last(“Status”) FROM db GROUP BY “Address”
)
WHERE “last” = ‘running’ GROUP BY “Address”
That works, but I want to count now how many are running. How would you do that? I should aggregate now over the results.
Thanks for the help.
