# Queries in Yandex WebSQL

You can use [Yandex WebSQL](../../websql/index.md) to run Yandex MPP Analytics for PostgreSQL cluster database operations.

WebSQL is a Yandex Cloud service that allows you to connect to managed database clusters and work with their databases, tables, schemas, and queries. It is a web-based tool that requires no additional authorization and simplifies working with Valkey™ commands by prompting the user.

To connect to a Yandex MPP Analytics for PostgreSQL cluster from WebSQL, create a connection:

1. Open the [folder dashboard](https://console.yandex.cloud).
1. Navigate to **Yandex MPP Analytics for PostgreSQL**.
1. Click the cluster name.
1. [Enable](update.md#change-additional-settings) **WebSQL access** in the cluster settings if it is not enabled yet.
1. Select the **WebSQL** tab.
1. Click **Create connection** and specify the following connection settings:
    * **Database type**: Greenplum®.
    * **Cluster folder**: Defaults to your current folder.
    * **Cluster**: Defaults to your current Yandex MPP Analytics for PostgreSQL cluster.
    * **Username**: Account you will use to connect to the cluster database.
    * User **password**.
    * **Databases** you want to connect to. You can only connect to the databases that exist in this cluster. The user account you specified must have access to them.
1. Click **Create**.

To open the query editor, click the connection you created on the **WebSQL** tab.
