MySQL

Overview

MySQL is an open-source relational database and one of the most widely deployed database engines in the world. It powers web applications, SaaS platforms, and data warehouses with features like InnoDB transactions, replication, JSON support, and full-text search. MySQL is available as a managed service on Amazon RDS, Aurora, Google Cloud SQL, Azure Database, PlanetScale, and Vitess.

Driver

Crate: mysql_async
Version: 0.36

Connection fields

Field	Description
Host	Hostname or IP address of the MySQL server.
Port	TCP port the server listens on.
Database	Name of the default database to connect to.
User	Authentication username.
Password	Authentication password. Stored in the macOS Keychain.
SSL Mode	One of `disable`, `prefer`, `require`, `verify-ca`, or `verify-full`.
Options	Additional connection parameters as `key1=val1&key2=val2`.

All connections also support an optional SSH tunnel. Configure the bastion host, port, user, and private key file under the SSH section of the connection form. See SSH tunnels for details.

URI format

Instead of filling in each field individually, you can paste a connection URI into the Paste URI field. Arris parses the URI and populates all fields automatically.

text Connection URI

mysql://user:password@host:3306/dbname?ssl-mode=REQUIRED

SSL & TLS

MySQL supports five SSL modes. Arris defaults to prefer, which uses SSL if the server supports it but falls back to unencrypted if not.

SSL Mode	Behavior
`disable`	Never use SSL. Not recommended for production.
`prefer`	Use SSL if available, fall back to unencrypted.
`require`	Always use SSL. Fail if the server does not support it.
`verify-ca`	Require SSL and verify the server certificate against a CA.
`verify-full`	Require SSL, verify the CA, and verify the server hostname matches the certificate.

Schema browser

Once connected, Arris fetches the schema tree from information_schema and organizes it into groups. In MySQL, databases act as schema-level containers — the tree shows databases at the top level, each containing its own object groups.

The schema tree displays the following object types, grouped by category:

Tables — regular tables
Views — views
Routines — functions and stored procedures
Events — scheduled events
Triggers — table-level triggers

Double-click any table or view to open it in a new tab with browse mode.

Supported SQL commands

Command	Notes
`SELECT`	Query data with `WHERE` filters, `JOIN`s, aggregates, and window functions.
`INSERT`	Insert single or multiple rows.
`UPDATE`	Update existing rows.
`DELETE`	Delete rows.
`CREATE` / `DROP`	Create and drop tables, views, and other schema objects.
