Using SQLLine With Apache Ignite

Command line tool for SQL connectivity.

Overview

Apache Ignite is shipped with the SQLLine tool – a console-based utility for connecting to relational databases and executing SQL commands. This documentation describes how to connect SQLLine to your cluster, as well as various supported SQLLine commands.

Connecting to Ignite Cluster

From your {IGNITE_HOME}/bin directory, run sqlline.sh -u jdbc:ignite:thin:[host] to connect SQLLine to the cluster. Substitute [host] with your actual value. For example:

./sqlline.sh --verbose=true -u jdbc:ignite:thin://127.0.0.1/
sqlline.bat --verbose=true -u jdbc:ignite:thin://127.0.0.1/

Use the -h or help option to see the various options available with SQLLine:

./sqlline.sh -h
./sqlline.sh --help
sqlline.bat -h
sqlline.bat --help

Authentication

If you have authentication enabled for your cluster, then from your {IGNITE_HOME}/bin' directory, run `jdbc:ignite:thin://[address]:[port];user=[username];password=[password] to connect SQLLine to the cluster. Substitute [address], [port], [username] and [password] with your actual values. For example:

./sqlline.sh --verbose=true -u "jdbc:ignite:thin://127.0.0.1:10800;user=ignite;password=ignite"
sqlline.bat --verbose=true -u "jdbc:ignite:thin://127.0.0.1:10800;user=ignite;password=ignite"

If you do not have authentication set, omit [username] and [password].

Note

Put JDBC URL in Quotes When Connecting from bash

Make sure to put the connection URL in " " quotes when connecting from a bash environment, as follows: "jdbc:ignite:thin://[address]:[port];user=[username];password=[password]"

After connecting to the cluster, you can execute SQL statements and SQLLine commands:

Create tables:

0: jdbc:ignite:thin://127.0.0.1/> CREATE TABLE City (id LONG PRIMARY KEY, name VARCHAR) WITH "template=replicated";
No rows affected (0.301 seconds)

0: jdbc:ignite:thin://127.0.0.1/> CREATE TABLE Person (id LONG, name VARCHAR, city_id LONG, PRIMARY KEY (id, city_id))WITH "backups=1, affinityKey=city_id";
No rows affected (0.078 seconds)

0: jdbc:ignite:thin://127.0.0.1/> !tables
+-----------+--------------+--------------+-------------+-------------+
| TABLE_CAT | TABLE_SCHEM  |  TABLE_NAME  | TABLE_TYPE  | REMARKS     |
+-----------+--------------+--------------+-------------+-------------+
|           | PUBLIC       | CITY         | TABLE       |             |
|           | PUBLIC       | PERSON       | TABLE       |             |
+-----------+--------------+--------------+-------------+-------------+

Define indexes:

0: jdbc:ignite:thin://127.0.0.1/> CREATE INDEX idx_city_name ON City (name);
No rows affected (0.039 seconds)

0: jdbc:ignite:thin://127.0.0.1/> CREATE INDEX idx_person_name ON Person (name);
No rows affected (0.013 seconds)

0: jdbc:ignite:thin://127.0.0.1/> !indexes
+-----------+--------------+--------------+-------------+-----------------+
| TABLE_CAT | TABLE_SCHEM  |  TABLE_NAME  | NON_UNIQUE  | INDEX_QUALIFIER |
+-----------+--------------+--------------+-------------+-----------------+
|           | PUBLIC       | CITY         | true        |                 |
