Getting Started with Oracle FreeSQL at FreeSQL.com

Overview

Oracle FreeSQL at FreeSQL.com is a free, browser‑based environment for learning, practicing, and prototyping SQL and PL/SQL on a real Oracle Database instance without installing any software. It runs entirely in the browser, giving users an always‑free personal schema and a safe sandbox to write, run, and share SQL scripts online.[1][2][3][4]

What Oracle FreeSQL Is

Oracle FreeSQL is the evolution of Oracle LiveSQL, rebranded and moved to FreeSQL.com while keeping the same core idea: an online SQL playground powered by an Oracle Database in the cloud. It is explicitly positioned as a completely free way to learn, build, and share SQL examples using Oracle technology.[2][4][1]

FreeSQL is designed for learners, educators, and developers who need real Oracle SQL, not a simplified emulator, and who want to access it without provisioning or paying for their own database instance. The service provides a personal schema for each registered user, which can be used both in the browser and via remote connections from tools like SQLcl, VS Code, or application code.[3][1][2]

Key Features (Always Free)

Oracle FreeSQL offers a set of features focused on hands‑on learning and rapid experimentation, with all functionality available for free.[1][2]

Free, browser‑based SQL worksheet where users can write and run SQL and PL/SQL directly against a live Oracle Database.[5][2][1]
Free personal schema per account, allowing users to create their own tables, views, and other objects without interfering with other users.[4][3][1]
Free access to a rich library of ready‑to‑run scripts and tutorials that can be executed as‑is or modified in the browser.[2][1]
Free community script sharing, enabling users to publish scripts and share links with students, colleagues, or the wider community.[1][2]
Free SQL*Net connectivity, so a user’s FreeSQL schema can be accessed from local tools and applications as a remote Oracle test database.[3][4][1]
Free use of sample data sets and a safe sandbox environment, allowing exploration and experimentation without risk to production systems.[4][1]

All of these capabilities are provided as part of the free Oracle FreeSQL service, with no time‑limited trials or paid tier required to use the platform for learning and experimentation.[1]

Typical Use Cases

Because FreeSQL is free, web‑based, and backed by a full Oracle Database, it supports a range of practical scenarios for different audiences.[2][1]

Students and self‑taught learners can practice SQL queries, joins, aggregations, and PL/SQL procedures against real data without installing any software.[1]
Educators can prepare example scripts, publish them in the FreeSQL library, and ask students to run and modify them directly in their browsers, with no local database setup.[2][1]
Career switchers and data professionals can use FreeSQL as a free training and practice ground to build confidence with Oracle SQL syntax and features.[2][1]
Application developers can prototype queries, functions, and package code in FreeSQL before integrating them into production applications.[3][1]
Engineers can use FreeSQL as a free remote Oracle test database by connecting to their schema from SQLcl, Java, Python, or other client tools over SQL*Net.[4][3]

In all of these cases, the key benefit is access to a fully managed Oracle environment that remains free to use and does not require any local installation or infrastructure.[1][2]

How the Website Works

The FreeSQL.com site centers on a web‑based SQL worksheet and a script library that users can access immediately, even before creating an account.[2][1]

Anonymous users can browse and run many example scripts directly in the browser, demonstrating that the core learning environment is free to explore without registration.[1]
Creating a free Oracle account unlocks a personal schema, script saving, and sharing features, while still keeping all usage free of charge.[2][1]

The top navigation typically includes options such as a worksheet, library, tutorials, and sign‑in controls, making it straightforward to move between writing code, browsing examples, and managing saved scripts. When a user runs a script, the results grid appears beneath the editor, showing query output, execution status, and any errors.[6][1]

Step‑by‑Step: Getting Started (No Installation, Always Free)

The following step‑by‑step guide shows how a new user can start using Oracle FreeSQL from scratch, entirely for free.[3][1][2]

1. Open the FreeSQL Website

Open a modern web browser such as Chrome, Edge, or Firefox.[1]
Navigate to https://FreeSQL.com, which loads the Oracle FreeSQL homepage and its browser‑based SQL interface.[6][1]
Confirm that the site loads the Oracle branding and FreeSQL name, indicating that you are in the official free Oracle environment.[6][1]

2. Explore Scripts Without Signing In

From the homepage or navigation menu, open the script library or tutorials section.[1]
Select any public example script, such as a basic SELECT over a sample table.
Click the Run or Execute button to run the script in the browser; the query executes against a real Oracle Database instance managed by Oracle at no cost to you.[5][1]
Modify the query (for example, change the WHERE clause) and run it again to see how the results change, using the free sandbox to experiment safely.[1]

At this stage, you are already using Oracle FreeSQL as a free online lab without creating an account.[1]

3. Create a Free Oracle Account

Click the Sign In button on the FreeSQL.com page.[6][1]
If you do not yet have an Oracle account, choose the option to create one; Oracle offers this account creation at no cost.[2][1]
Complete the registration form and verify your email as prompted.[1]
Return to FreeSQL.com and sign in with your new free Oracle account.[1]

Once signed in, a personal schema is provisioned for you in the FreeSQL environment, remaining free to use for running and saving your own SQL and PL/SQL code.[3][1]

4. Open the SQL Worksheet

After signing in, click the Worksheet option in the FreeSQL navigation.[6][1]
The worksheet displays an editor pane where you can type SQL and PL/SQL and a results pane where query results appear.[1]
Ensure that the connection indicator (if shown) reflects your personal schema, confirming that code runs in your own free database space.[3][1]

From this worksheet, you can write any valid Oracle SQL or PL/SQL statements and run them at no cost as part of the FreeSQL service.[2][1]

Step‑by‑Step: Running Your First Custom Query

Once the worksheet is open, the next step is to run a simple custom query in your free schema.[3][1]

In the worksheet editor, type a simple query such as SELECT 1 AS demo_col FROM dual;.
Click the Run or Execute button; FreeSQL sends the statement to the underlying Oracle Database and displays the result in the output grid.[1]
Observe the returned row showing demo_col = 1, confirming that your query executed successfully in the free Oracle environment.[1]
Next, explore sample tables available in your schema or in shared schemas; many scripts in the library reference sample data such as customers and orders, which can be queried and joined.[5][4][1]
Create your own table, for example with a CREATE TABLE statement, and insert rows using INSERT statements; these operations are persisted in your free schema.[3][1]

All of these actions—creating tables, inserting data, and querying—are carried out on an Oracle Database instance that Oracle provides as part of the free FreeSQL offering.[3][1]

One of the strengths of Oracle FreeSQL is its script library and sharing capabilities, which are also provided for free.[2][1]

After writing a useful script in the worksheet, use the Save option to store it under your account.
Provide a name, description, and optional tags so others can discover it, following the patterns used in existing library entries.[2][1]
Mark the script as public if you want to share it with the community; this makes it visible in the FreeSQL library alongside other community contributions.[2][1]
Copy the shareable link generated by FreeSQL and send it to students, team members, or friends; anyone with a browser can open and run it for free.[2][1]

This free sharing mechanism allows instructors to distribute executable examples instead of static screenshots and enables collaborative learning and code review around SQL and PL/SQL.[2][1]

Using FreeSQL as a Remote Test Database (SQL*Net)

Beyond the browser, FreeSQL can act as a free remote Oracle test database by allowing SQL*Net connections to a user’s schema.[4][3]

FreeSQL provides connection details, including host, port, service name, username, and a generated password, which can be used in tools like SQLcl or in application code.[4][3]
Users can reset or regenerate a database password from the FreeSQL interface, ensuring secure access while keeping the schema free to use.[4][3]

A typical SQLcl connection string to a FreeSQL schema looks like sql '<SCHEMA>/<PASSWORD>@//db.freesql.com:1521/26ai_un3c1', which connects to the hosted Oracle AI Database backing FreeSQL. This means developers can run integration tests, prototypes, and experiments against a real Oracle Database instance without paying for their own database server.[4][3]

Embedding and Integrating FreeSQL Scripts

Oracle highlights that FreeSQL scripts can be embedded in external content such as blog posts, tutorials, and documentation, providing interactive, executable SQL examples at no charge. Authors can include links or embedded sandboxes that allow readers to run and modify queries directly, leveraging the free Oracle infrastructure behind FreeSQL.[7][1]

For documentation sites, learning platforms, and technical blogs, this capability provides a way to offer live Oracle SQL exercises without requiring users to set up any local database or cloud account beyond the free Oracle login used by FreeSQL.[7][1]

Who Should Use Oracle FreeSQL

Oracle FreeSQL is aimed at a broad audience, with all core functionality offered for free use.[2][1]

Students and beginner programmers learning SQL and PL/SQL benefit from immediate, no‑install access to real Oracle features and syntax.[1]
Educators and training providers can build courses around FreeSQL, relying on its free availability to eliminate installation issues in classrooms and remote courses.[2][1]
Experienced developers and DBAs can use FreeSQL as a convenient, free scratchpad for testing queries or demonstrating Oracle features.
Hobbyists and career switchers can use FreeSQL to build a SQL portfolio by publishing scripts and examples in the community library.[2][1]

Because the service remains free and is managed by Oracle, organisations can also recommend FreeSQL as an approved learning resource for their staff without incurring additional licensing or infrastructure costs.[1][2]
