Hi

I am novice and still learning how to use canvas feature. I would like to know how to derive bucket aggregation in canvas preferably with some example.  
Something like below , how it can be written in essql?

GET jtlresults-cttd3/\_search  
{  
"aggs" : {  
"time\_ranges" : {  
"range" : {  
"field" : "elapsed",  
"keyed" : true,  
"ranges" : [  
{ "key" : "total", "from" :0 },  
{ "key" : "low", "to" : 2000 },  
{ "key" : "medium", "from" : 2000, "to" : 5000 },  
{ "key" : "high", "from" : 5000 }  
]  
}  
}  
}  
}

Hi @sujeet.ssv,

yes this is possible by using the `CASE` statement as described here: [https://www.elastic.co/guide/en/elasticsearch/reference/7.6/sql-functions-conditional.html#sql-functions-conditional-case-groupby-custom-buckets](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/sql-functions-conditional.html#sql-functions-conditional-case-groupby-custom-buckets)

```auto
SELECT count(*) AS count,
  CASE WHEN NVL(languages, 0) = 0 THEN 'zero'
    WHEN languages = 1 THEN 'one'
    WHEN languages = 2 THEN 'bilingual'
    WHEN languages = 3 THEN 'trilingual'
    ELSE 'multilingual'
  END as lang_skills
FROM employees
GROUP BY lang_skills
ORDER BY lang_skills;

```

Just put the ranges you want to see in the `WHEN` conditions
