i have a query that is working well in Influx:
SELECT delta FROM "measures" WHERE $timeFilter AND ("operation_id" =~ /^$operationId$/) AND ("meter_id" =~ /^$meterId$/) GROUP BY meter_id
With variable operationId and meterId having “all” value
In postgres ( timescaleDB ), this is my equivalent:
SELECT time_bucket('30 minutes', time) AS "time", sum(delta), meter_id FROM measures WHERE $__timeFilter("time") AND operation_id = $operationId AND meter_id = $meterId AND GROUP BY time, meter_id ORDER BY time;
As I have a value each 30 min, it can be considerated as equivalent, even if I should improve this query.
Here, the graf is displaying, but when I set $meterId to “all” value, I will have an error in the query:
pq: syntax error at or near ","
Not very verbose.
I tried to use the same regex for postgres:
"operation_id" =~ /^$operationId$/
operation_id = $operationId
but it is not working.
Also, a weird thing that maybe not related to the issue, is that I have autocompletion for operationId variable but not for meterId variable.
Any idea how to translate the influx regex ? Thing is I don’t really understand this regex, so it makes me difficult translate it.
