SQL Lite aggregare on non grouped Column

Elastic Stack Elasticsearch
1

Hi @leandrojmp ,

I have a requirement where I need to apply order on a filed in Elasticsearch which is formed dynamically on the fly and it is not part of original index.

My Sample document looks like

{
  "deviceType": "desktop",
  "personalizedSignal": "sdf",
  "componentPosition": "top",
  "count": 10,
  "environment": "sdfsdf",
  "pageType": "hp",
  "eventName": "click",
  "analyticsID": "sdfsdf",
  "timestamp": 1691589600000
}


{
  "deviceType": "desktop",
  "personalizedSignal": "sdf",
  "componentPosition": "top",
  "count": 10,
  "environment": "sdfsdf",
  "pageType": "hp",
  "eventName": "impression",
  "analyticsID": "sdfsdf",
  "timestamp": 1691589600000
}```

I am running sqllite statement from Superset where I need to display and order by a column which is determined on the fly


Query

GET _sql?format=txt
{
"query": """
SELECT analyticsID,
impression,
click,
(1.0 * click/impression) as CTR
from
(select analyticsID,
SUM(case
when eventName='impression' then (count)
end) impression,
SUM(case
when eventName='click' then (count)
end) click
from "rollup-dco-dummy-index"
group by analyticsID) order by CTR DESC
"""
}


I am getting an error like below

{
  "error": {
    "root_cause": [
      {
        "type": "verification_exception",
        "reason": """Found 1 problem
line 15:41: Cannot order by non-grouped column [CTR], expected [analyticsID] or an aggregate function"""
      }
    ],
    "type": "verification_exception",
    "reason": """Found 1 problem
line 15:41: Cannot order by non-grouped column [CTR], expected [analyticsID] or an aggregate function"""
  },
  "status": 400
}

Hello,

Sorry, I cannot help as I never used the SQL interface in Elasticsearch, I have no experience with it.
