Getting Started with SQL
editGetting Started with SQL
editTo start using Elasticsearch SQL, create an index with some data to experiment with:
PUT /library/book/_bulk?refresh
{"index":{"_id": "Leviathan Wakes"}}
{"name": "Leviathan Wakes", "author": "James S.A. Corey", "release_date": "2011-06-02", "page_count": 561}
{"index":{"_id": "Hyperion"}}
{"name": "Hyperion", "author": "Dan Simmons", "release_date": "1989-05-26", "page_count": 482}
{"index":{"_id": "Dune"}}
{"name": "Dune", "author": "Frank Herbert", "release_date": "1965-06-01", "page_count": 604}
And now you can execute SQL using the SQL REST API right away:
POST /_sql?format=txt
{
"query": "SELECT * FROM library WHERE release_date < '2000-01-01'"
}
Which should return something along the lines of:
author | name | page_count | release_date ---------------+---------------+---------------+------------------------ Dan Simmons |Hyperion |482 |1989-05-26T00:00:00.000Z Frank Herbert |Dune |604 |1965-06-01T00:00:00.000Z
You can also use the SQL CLI. There is a script to start it shipped in x-pack’s bin directory:
$ ./bin/elasticsearch-sql-cli
From there you can run the same query:
sql> SELECT * FROM library WHERE release_date < '2000-01-01';
author | name | page_count | release_date
---------------+---------------+---------------+------------------------
Dan Simmons |Hyperion |482 |1989-05-26T00:00:00.000Z
Frank Herbert |Dune |604 |1965-06-01T00:00:00.000Z
