Elasticsearch ships with a script to run the SQL CLI in its
You can pass the URL of the Elasticsearch instance to connect to as the first parameter:
$ ./bin/elasticsearch-sql-cli https://some.server:9200
If security is enabled on your cluster, you can pass the username
and password in the form
to the SQL CLI:
$ ./bin/elasticsearch-sql-cli https://sql_user:firstname.lastname@example.org:9200
Once the CLI is running you can use any query that Elasticsearch supports:
sql> SELECT * FROM library WHERE page_count > 500 ORDER BY page_count DESC; author | name | page_count | release_date -----------------+--------------------+---------------+--------------- Peter F. Hamilton|Pandora's Star |768 |1078185600000 Vernor Vinge |A Fire Upon the Deep|613 |707356800000 Frank Herbert |Dune |604 |-144720000000 Alastair Reynolds|Revelation Space |585 |953078400000 James S.A. Corey |Leviathan Wakes |561 |1306972800000
The jar containing the SQL CLI is a stand alone Java application and the scripts just launch it. You can move it around to other machines without having to install Elasticsearch on them. Without the already provided script files, you can use a command similar to the following to start the SQL CLI:
$ ./java -jar [PATH_TO_CLI_JAR]/elasticsearch-sql-cli-[VERSION].jar https://some.server:9200
$ ./java -cp [PATH_TO_CLI_JAR]/elasticsearch-sql-cli-[VERSION].jar org.elasticsearch.xpack.sql.cli.Cli https://some.server:9200
The jar name will be different for each Elasticsearch version (for example
thus the generic
VERSION specified in the example above. Furthermore,
if not running the command from the folder where the SQL CLI jar resides,
you’d have to provide the full path, as well.
Apart from SQL queries, CLI can also execute some specific commands:
allow_partial_search_results = <boolean>(default
true, returns partial results if there are shard request timeouts or shard failures. If
false, returns an error with no partial results.
sql> allow_partial_search_results = true; allow_partial_search_results set to true
fetch_size = <number>(default
- Allows to change the size of fetches for query execution. Each fetch is delimited by fetch separator (if explicitly set).
sql> fetch_size = 2000; fetch size set to 2000
fetch_separator = <string>(empty string by default)
- Allows to change the separator string between fetches.
sql> fetch_separator = "---------------------"; fetch separator set to "---------------------"
lenient = <boolean>(default
false, Elasticsearch SQL returns an error for fields containing array values. If
true, Elasticsearch SQL returns the first value from the array with no guarantee of consistent results.
sql> lenient = true; lenient set to true
- Returns server information.
sql> info; Node:mynode Cluster:elasticsearch Version:8.3
- Closes the CLI.
sql> exit; Bye!
- Clears the screen.
- Prints Elastic logo.
