After doing this, you need to restart the Elasticsearch server. Otherwise you may get errors like Invalid index name [sql], must not start with '']; ","status":400}.

Basic Usage

On elasticsearch 1.x / 2.x, visit the elasticsearch-sql web front-end:

http://localhost:9200/_plugin/sql/

On elasticsearch 5.x/6.x, use elasticsearch sql site chrome extension (make sure to enable cors on elasticsearch.yml). Alternatively, download and extract site, then start the web front-end like this:

cd site-server
npm install express --save
node node-server.js

Simple query

curl -X GET "localhost:9200/_sql" -H 'Content-Type: application/json' -d'select * from indexName limit 10'

Explain SQL to elasticsearch query DSL

curl -X GET "localhost:9200/_sql/_explain" -H 'Content-Type: application/json' -d'select * from indexName limit 10'

SQL Usage

Query

  SELECT * FROM bank WHERE age >30 AND gender = 'm'

Aggregation

  select COUNT(*),SUM(age),MIN(age) as m, MAX(age),AVG(age)
  FROM bank GROUP BY gender ORDER BY SUM(age), m DESC

Delete

  DELETE FROM bank WHERE age >30 AND gender = 'm'

Beyond SQL

Search

  SELECT address FROM bank WHERE address = matchQuery('880 Holmes Lane') ORDER BY _score DESC LIMIT 3

Aggregations

range age group 20-25,25-30,30-35,35-40

  SELECT COUNT(age) FROM bank GROUP BY range(age, 20,25,30,35,40)

range date group by day

  SELECT online FROM online GROUP BY date_histogram(field='insert_time','interval'='1d')

range date group by your config

  SELECT online FROM online GROUP BY date_range(field='insert_time','format'='yyyy-MM-dd' ,'2014-08-18','2014-08-17','now-8d','now-7d','now-6d','now')

ES Geographic

  SELECT * FROM locations WHERE GEO_BOUNDING_BOX(fieldname,100.0,1.0,101,0.0)

Select type
```
  SELECT * FROM indexName/type
```

SQL Features

SQL Select
SQL Delete

SQL round
- eg: round(10.135, 2) --> 10.14
SQL sqrt
SQL concat_ws
SQL union and minus
SQL case when
- can use "in"、"not in" judge in case when clause
- can execute simple calculation in case when clause, eg : case when 1 = 1 then field_1 + field_2 else 0 end
SQL if
- select if(sex='1','男','女') from t_user;
SQL limit
- can set aggregation bucket size and shard size by setting limit, shardSize = 20 * bucketSize
- eg: select city,count(*) as user_count from t_user group by city limit 100;
- on the above example, the bucket size is 100, shard size is 20*100 = 2000
