Is it possible to use the SHOW TAG VALUES statement (with all trailing
clauses like WITH and WHERE) inside SELECT statement ??
Particularly inside a WHERE clause wihin the SELECT statemet.
Let me try to use an example:
I am trying to select cpu_usage metric from a Datacenter measurement with a
tag called Building, I want to (sort of) search for when this tag's value
is in the result of SHOW tag values statement for a different measurement.
SELECT "cpu_usage" from sixty_weeks."Datacenter" WHERE time > '2016-10-16'
AND machine =~ /.*Rack1.*/ AND (*"Building" IN* (SHOW TAG VALUES FROM
sixty_weeks."floormapping" WITH KEY = "buildings" WHERE
"active" =~ /$var1$/ ))
I haven't been able to make this work, so I am wondering now: is this even
possible? and how to do it if yes?
