Oracle

Available on: Cloud Free, Cloud Professional, Cloud Enterprise, Self-Hosted Enterprise

Introduction

Hasura enables you to connect to Oracle databases to automatically build a GraphQL API based on your database schema.

At present, our Oracle integration is available in Hasura Cloud and Docker environments, where you can run Hasura GraphQL Engine and connect the Oracle GraphQL Data Connector to it. For more information on GraphQL Data Connectors check out our blog post on the topic.

To get started with Oracle:

• In Hasura Cloud, check out our Getting Started with Oracle in Hasura Cloud guide
• In a Docker environment, check out our Getting Started with Docker guide

Using Kubernetes?

We have Helm charts available for deploying Hasura on Kubernetes. Check out more information here and see the enterprise-stack here.

Supported versions

1. Hasura GraphQL Engine v2.24.0 onwards
2. Hasura supports most databases with standard implementations of Oracle 18.0 and higher including Amazon RDS.

Supported features

Hasura currently supports queries, mutations (INSERT, UPDATE, DELETE), table relationships, remote relationships and permissions on Oracle.

Note that Hasura doesn't yet support the ability to modify the database schema for Oracle, so the database you connect to should already contain tables and data. You should also ideally have access to it outside of Hasura to modify the schema.

Managing data with the Hasura Console

The Hasura Console is a web UI that allows you to manage your data and metadata. It is available at http://localhost:8080/console when you run Hasura locally, or from your project's Console endpoint when you use Hasura Cloud.

The data-management features (such as creating tables) are available in the Data tab. You can access your GraphQL API in the API tab and interact with it using the GraphiQL interface.

Console support

We recommend using your preferred Oracle client instead. The Hasura Console is designed to be a tool for managing your GraphQL API, and not a full-fledged database management tool.
