Solved : Noob question over data management in InfuxDB

Thank you for your help.

I get the following error :

error parsing query: retention policy not supported at line 1, char 1

If I use this formula :

drop series from “domoticz”.“autogen”.“device_exterieur_temp” where time > “2018-02-07T05:00:00Z” and time < “2018-02-08T16:17:00Z”

I get no error, but nothing happens, and data is still here.

If I use this :

select * from “domoticz”.“autogen”.“device_salon_temp” where time > ‘2018-02-08T14:00:00Z’ and time < ‘2018-02-08T15:00:00Z’

I get :

invalid operation: time and *influxql.VarRef are not compatible
I’ve tried numerous combinations of syntax (no quotes, simple quotes, double, etc.), none worked. I googled before, but it doesn’t work for me :
