Oracle Database

Overview

Oracle Database is an enterprise relational database known for its scalability, PL/SQL procedural language, Real Application Clusters (RAC), and advanced features like partitioning, flashback queries, and JSON support. Oracle is available on-premises, on Oracle Cloud Infrastructure (OCI), Amazon RDS, and Azure.

Driver

Crate: oracle-rs
Version: 0.1

Connection fields

Field	Description
Host	Hostname or IP address of the Oracle server.
Port	Oracle Net listener port.
Database	Service name or SID 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

oracle://user:password@host:1521/service_name

SSL & TLS

Oracle 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 Oracle data dictionary views and organizes it into groups. The tree shows schemas 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 and materialized views
Routines — functions and stored procedures
Sequences — sequences
Types — user-defined types
Triggers — table-level triggers
Indexes — B-tree, bitmap, and other index types

Double-click any table, view, or materialized 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.
