SQL CLI

SQL CLI is a stand-alone Python application that you can launch with the odfesql command.

Install the SQL plugin to your Elasticsearch instance, run the CLI using MacOS or Linux, and connect to any valid Elasticsearch end-point.

SQL CLI

Features

SQL CLI has the following features:

  • Multi-line input
  • Autocomplete for SQL syntax and index names
  • Syntax highlighting
  • Formatted output:
    • Tabular format
    • Field names with color
    • Enabled horizontal display (by default) and vertical display when output is too wide for your terminal, for better visualization
    • Pagination for large output
  • Works with or without security enabled
  • Supports loading configuration files
  • Supports all SQL plugin queries

Install

Launch your local Elasticsearch instance and make sure you have the SQL plugin installed.

To install the SQL CLI:

  1. We suggest you install and activate a python3 virtual environment to avoid changing your local environment:
    pip install virtualenv
    virtualenv venv
    cd venv
    source ./bin/activate
    
  2. Install the CLI:
    pip3 install odfe-sql-cli
    

The SQL CLI only works with Python 3.

  1. To launch the CLI, run:
    odfesql https://localhost:9200 --username admin --password admin
    

    By default, the odfesql command connects to http://localhost:9200.

Configure

When you first launch the SQL CLI, a configuration file is automatically created at ~/.config/odfesql-cli/config (for MacOS and Linux), the configuration is auto-loaded thereafter.

You can configure the following connection properties:

  • endpoint: You do not need to specify an option, anything that follows the launch command odfesql is considered as the endpoint. If you do not provide an endpoint, by default, the SQL CLI connects to http://localhost:9200.
  • -u/-w: Supports username and password for HTTP basic authentication, such as with the security plugin or fine-grained access control for Amazon Elasticsearch Service.
  • --aws-auth: Turns on AWS sigV4 authentication to connect to an Amazon Elasticsearch endpoint. Use with the AWS CLI (aws configure) to retrieve the local AWS configuration to authenticate and connect.

For a list of all available configurations, see clirc.

Using the CLI

  1. Save the sample accounts test data file.

  2. Index the sample data.
    curl -H "Content-Type: application/x-ndjson" -POST https://localhost:9200/data/_bulk -u 'admin:admin' --insecure --data-binary "@accounts.json"
    
  3. Run a sample SQL command:
    SELECT * FROM accounts;
    

By default, you see a maximum output of 200 rows. To show more results, add a LIMIT clause with the desired value.

Query options

Run a single query with the following options:

  • --help: Help page for options
  • -q: Follow by a single query
  • -f: Specify JDBC or raw format output
  • -v: Display data vertically
  • -e: Translate SQL to DSL

CLI options

  • -p: Always use pager to display output
  • --clirc: Provide path for the configuration file
