SQL and PPL CLI

SQL and PPL CLI

The SQL and PPL command line interface (CLI) is a standalone Python application that you can launch with the opensearchsql command.

To use the SQL and PPL CLI, install the SQL plugin on your OpenSearch instance, run the CLI using MacOS or Linux, and connect to any valid OpenSearch endpoint.

Features

The SQL and PPL CLI has the following features:

Multi-line input
PPL support
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 OpenSearch instance and make sure you have the SQL plugin installed.

Install the CLI:
```
pip3 install opensearchsql
```

The SQL CLI only works with Python 3.

To launch the CLI, run:
```
opensearchsql https://localhost:9200 --username admin --password admin
```
By default, the opensearchsql command connects to http://localhost:9200.

Configure

When you first launch the SQL CLI, a configuration file is automatically created at ~/.config/opensearchsql-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 opensearchsql 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 OpenSearch Service.
--aws-auth: Turns on AWS sigV4 authentication to connect to an Amazon OpenSearch 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

Run the CLI tool. If your cluster runs with the default security settings, use the following command:
```
opensearchsql --username admin --password admin https://localhost:9200
```
If your cluster runs without security, run:
```
opensearchsql
```
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.

To exit the CLI tool, select Ctrl+D.

Using the CLI with PPL

Run the CLI by specifying the query language:
```
opensearchsql -l ppl <params>
```

Execute a PPL query:

source=accounts | fields firstname, lastname

Query options

Run a single query with the following command line 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

--help: Help page for options
-l: Query language option. Available options are sql and ppl. Default is sql
-p: Always use pager to display output
--clirc: Provide path for the configuration file
