Online SQLAlchemy Compiler & Python ORM Playground - Run & Practice SQLAlchemy Online

RustcodeWeb provides an instant, pure client-side online SQLAlchemy compiler and Python ORM playground powered by Pyodide WebAssembly. Write, execute, test, and practice SQLAlchemy 2.0 queries, declarative models, and database operations directly in your browser with zero server latency, instant tabular results, and pre-seeded relational tables.

Key Capabilities & Features

  • Pure In-Browser Python & SQLAlchemy Execution: Full Python 3.12 and SQLAlchemy 2.0 runtime powered by Pyodide WebAssembly executing directly inside your browser client.
  • Zero Setup Required: Start querying immediately with 6 interconnected relational database models (Department, Employee, Customer, Order, Project, EmployeeProject).
  • Instant Tabular Visualization: Query results automatically render as clean, interactive, sortable tables with row counts and execution metrics.
  • Comprehensive ORM Query Presets: Preloaded templates covering select(), filter(), join(), group_by(), scalar subqueries, insert/update statements, and raw text() SQL.
  • Interactive Model Schema & Live Data Browser: Inspect all table columns, primary key definitions, relationship attributes, and browse records with smooth modal navigation.
  • Professional Code Editor: High-contrast syntax highlighting, bracket matching, indentation guides, code formatting, and light/dark theme switching.

Supported SQLAlchemy & Python Concepts

Practice modern SQLAlchemy 2.0 declarative style and Core queries online:

  • Select Statements: select(), filter(), where(), order_by(), limit(), offset(), distinct().
  • Relational Joins: select().join(), outerjoin(), multi-table relationships, and junction table queries.
  • Aggregations & Grouping: func.count(), func.sum(), func.avg(), func.round(), and group_by() with having().
  • Subqueries & Expressions: Scalar subqueries, .exists(), in_(), case(), and func expressions.
  • DML Operations: session.add(), session.commit(), session.rollback(), insert(), and update().
  • Raw SQL Integration: text() queries seamlessly executed within the ORM session.

Frequently Asked Questions (FAQ)

How do I run SQLAlchemy code online?
Write your SQLAlchemy query assigned to the output variable in the code editor and click 'Run' or press Ctrl+Enter. The query executes inside the Pyodide WebAssembly worker and results are displayed in the results table.
Does this require an external database or Python server?
No. The entire Python runtime and SQLite database engine run 100% locally in your web browser via WebAssembly with complete privacy and zero server queues.
What version of SQLAlchemy is supported?
The playground runs the latest SQLAlchemy 2.x standard declarative mapping syntax with type annotations and modern select() constructs.
