Hi all 
I have a query that gives me a result of many tables instead of a single table with many rows and I would like some guidance in how to address this, and maybe a brief explain why I see this behavior in the first place. Being more verse with SQL, the result is not what I would expect to see.
Query
from(bucket: "cust-csg")
|> range(start: 2021-06-01T00:00:00Z, stop: 2021-06-30T23:59:59Z)
|> filter(fn: (r) => r["_measurement"] == "MessageTrace")
|> filter(fn: (r) => r["_field"] == "RecipientCountDelivered")
|> group(columns: ["UserPrincipalName"])
|> aggregateWindow(every: 30d, fn: sum, createEmpty: false)
|> drop(columns: ["_time", "_start", "_stop"])
|> rename(columns: {_value: "June"})
Expected result
| UserPrincipalName | June |
|---|---|
| sales1@… | 104 |
| sales2@… | 39 |
| … | … |
| … | … |
Actual result
As a bonus, is there any date modifier that could more easily give me the range of a given month? E.g. input of ‘2021-06’ would result in a range between 2021-06-01T00:00:00Z and 2021-06-30T23:59:59Z.
Thanks everyone!
Edit
I think a final |> group(columns: []) statement do just that.
