So what I’m looking for is to do math operation (specifically subtraction in this case) between value::field where domain = D1 and where domain = D2.
This is my data
time GRP_ID MCCMNC domain host value
---- ------ ------ ------ ---- -----
2018-08-13T12:10:00Z NON-DEFLTCELLGRP 310410 D1 host1 900540
2018-08-13T12:10:00Z NON-DEFLTCELLGRP 310410 D1 host2 900540
2018-08-13T12:10:00Z NON-DEFLTCELLGRP 310410 D1 host6 900540
2018-08-13T12:10:00Z NON-DEFLTCELLGRP 310410 D2 host7 900533
2018-08-13T12:10:00Z NON-DEFLTCELLGRP 310410 D2 host8 900533
2018-08-13T12:10:00Z NON-DEFLTCELLGRP 310410 D2 host9 900533
2018-08-13T12:10:00Z NON-DEFLTCELLGRP 310410 D2 host10 900533
So essentially this…but of course this doesn’t work:
(SELECT max(value) AS "MAX_OF_D1" from "glsDB_CTS" WHERE "MCCMNC" = '310410' AND "GRP_ID" = 'NON-DEFLTCELLGRP' AND "domain" = 'D1' group by time(5m)) -
(SELECT max(value) AS "MAX_OF_D2" from "glsDB_CTS" WHERE "MCCMNC" = '310410' AND "GRP_ID" = 'NON-DEFLTCELLGRP' AND "domain" = 'D2' group by time(5m))
…and the result would be 7 (because 900540 - 900533)
time value
---- ------
