Hi,

first thanks for this awesome software. But I have some trouble and I don't know how to proceed. First I try to find out what else I could provide for this report to be a good bug report.

First, I use the latest version (v1.14.0) from openSUSE build Service. I know, I should compile it by my self to avoid any other causes for this behavior. But for now I still use this package from there

When support for Metrics Insights was added to the GetMetricData api, a few new error codes were introduced. These should be handled as an error or possibly as a warning.

In https://github.com/taosdata/TDengine/blob/develop/src/client/src/tscPrepare.c, Local variable loopCont is assigned only once, to a constant value, making it effectively constant throughout its scope. If this is not the intent, examine the logic to see if there is a missing assignment that would make loopCont not remain constant.

So the 1567th line should be removed.

Relevant telegraf.conf:

[[inputs.openweathermap]]
  app_id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  

Describe the bug

QuestDB throws an error if my query returns 0 rows when using SAMPLE BY. It works fine and responds 0 row found without SAMPLE BY.

My query (I run it on QuestDB web console directly)

SELECT ts, pair, side, round(nsum(size)) as size
FROM liquidations
WHERE pair = 'ETC-USDT-PERP' and side = 'sell' and size > 500
SAMPLE BY 1m
ALIGN TO CALENDAR WITH OFFSET '00:00'
