You can use Yandex WebSQL to send SQL queries to Managed Service for MySQL® cluster databases.
WebSQL is a Yandex Cloud service that allows you to connect to managed database clusters, work with databases, tables, and schemas, and run queries. It is a web-based tool that requires no additional authentication and simplifies working with SQL commands by suggesting prompts.
To connect to a Managed Service for MySQL® cluster from WebSQL, create a connection:
- Go to Managed Service for MySQL.
- Click the cluster name.
- Enable WebSQL access in the cluster settings if it is not on yet.
- Select the WebSQL tab.
- Click Create connection and specify the following connection settings:
- Connection name.
- Database type: MySQL®.
- Cluster: Defaults to your current MySQL® cluster.
- Username you will use to connect to the database in the cluster.
- Password: User password.
- Databases: List of databases you want to access. You can only connect to the databases within the current cluster. The user account you specified must have permissions to access these databases.
- Click Create.
To open the SQL editor, click the created connection on the WebSQL tab.
