CQL console

The Cassandra Query Language SHell (CQLSH) is a command line shell for interacting with your database through Cassandra Query Language (CQL). This tool provides a useful interface for accessing the database and issuing CQL commands.

Embedded Astra DB CQL shell

Each DataStax Astra DB database includes an embedded CQL shell instance. In Astra Portal, navigate to your database and click the CQL Console tab to open a CQLSH instance that is connected to your database. Issue CQL commands directly to your Astra DB database without navigating outside of your browser.

To see the CQL console in a full browser window, use this URL format:

database_id-region.apps.astra.datastax.com/cqlsh

For example, 2f0c6j8b-9790-4276-a16c-0cd7b055344a-us-east1.apps.astra.datastax.com/cqlsh

Once you open the CQL shell in Astra, you will automatically be signed in and connected to your database.

Results

You can now run CQL commands in your embedded CQL shell.

Alternatively, you can connect to your Astra DB database using the standalone version of CQLSH.

Standalone CQL shell

Instead of using the native CQL shell that is included in DataStax Enterprise (DSE), the standalone CQLSH client is a separate, lightweight tool you can use to interact with your database.

Each DataStax Astra DB database includes an embedded CQL shell instance. In Astra Portal, navigate to your database and click the CQL Console tab to open a CQLSH instance that is connected to your database.

Prerequisites

Download CQLSH. Choose the version for Astra DB.
Create an Astra DB database.
Python version with TLS Support. A minimum of 2.7.12. More details here.

Working with secure connect bundle

Downloading secure connect bundle

To connect to your Astra DB database using the drivers, download the secure connect bundle from the DataStax Astra Portal that contains the connection credentials.

Open your Astra Portal and select your database.

On the Overview page, select Connect.

In the Select a Method section, select Drivers and then Native from the dropdown menu to select your driver type from the list to load language-specific instructions.

Java is available as a Legacy, Native, and Cloud driver. Node.js is available as Native and Cloud drivers. Python is available as Legacy and Native drivers.

If you have multiple regions, select the region you want to connect to from the dropdown menu for instructions.

The bundle URL is the same for all languages.

Click Download Bundle.

If you have multiple regions, you will have the option to download a bundle for each region from the expanded Download Bundle drop-down menu.

The secure-connect-database_name.zip file downloads, which contains the security certificates and credentials for your database.

Sharing secure connect bundle

Although teammates can access your Astra DB database, it will not display in their list of available databases under My Databases in Astra Portal.

After you create an Astra DB database, you can grant access to other members of your team by providing them with the database credentials and connection details for your database.

Be careful when sharing connection details. Providing this information to another user grants them access to your Astra DB database and ownership capabilities, such as making modifications to the database.

For security, delete downloaded connection credentials after sending them to your teammate.

Secure connect bundle contents

The Secure Connect Bundle (SCB) contains the following files:

File Contents

File	Contents
`ca.crt`	DataStax’s Certificate Authority public certificate
`cert`	A certificate, unique to the specific SCB
`key`	A private key, unique to the specific SCB
`cert.pfx`	A PFX formatted archive containing the certificate and the private key
`config.json`	A configuration file with information on how to securely connect to the Astra DB instance associated with the SCB
`cqlshrc`	A CQLSH profile containing CQL shell session settings
`identity.jks`	A Java keystore file containing the aforementioned cert & key files
`trustStore.jks`	A Java keystore file containing the aforementioned ca.crt

ca.crt

DataStax’s Certificate Authority public certificate

cert

A certificate, unique to the specific SCB

key

A private key, unique to the specific SCB

cert.pfx

A PFX formatted archive containing the certificate and the private key

config.json

A configuration file with information on how to securely connect to the Astra DB instance associated with the SCB

cqlshrc

A CQLSH profile containing CQL shell session settings

identity.jks

A Java keystore file containing the aforementioned cert & key files

trustStore.jks

A Java keystore file containing the aforementioned ca.crt

Alternatively, have a teammate provide access to their Astra database.

Procedure

Change to the directory where you downloaded the CQLSH tarball and then extract it:

$ cd /<download_directory>
$ tar -xvf cqlsh-astra-<date>-bin.tar.gz

date - The date that the tarball was released, such as 20210304.

From the directory where you extracted the CQLSH tarball, run the cqlsh script from the command line:

$ cd /cqlsh-astra
$ ./bin/cqlsh -u **clientID** -p **clientSecret** -b /path/to/secure-connect**database_name**.zip

Use the -b option to specify the location of the secure connect bundle that you downloaded for your database. Pass the Client Id and Client Secret for your database role using the -u and -p options. For more, see Manage application tokens.

username - Client ID for the database role.
password - Client secret for the specified Client ID.
database_name - Name of the Astra DB database to which you want to connect. Include the absolute path to the secure connect bundle for the database, such as /Users/myuser/Downloads/secure-connect-database123.zip.

Configure the cqlshrc file If you do not want to pass the secure connect bundle on the command line every time, set up the location in your cqlshrc file.

In the [authentication] section of the cqlshrc file in ~/.cassandra, include the Client ID and Client Secret from your application token. Configure the [connection] section of the cqlshrc file in ~/.cassandra to include the path to your secure connect bundle.

[authentication]
username = clientID
password = clientSecret

[connection]
secure_connect_bundle = **/path/to/**secure-connect-**database_name**.zip

Results

You are connected directly to your database using CQLSH.

Switch to your KEYSPACE, where you can issue CQL commands to create tables, insert data, and manage database resources:

USE keyspace_name;

An alternative way to connect to the CQL shell is to use the Astra CLI. This option downloads and configures CQL shell for you, including downloading Secure Connect Bundle and setting up the token to the Astra account. For more on installing and getting started, see Astra CLI documentation.
