Oracle SQL user?

This browser version uses DuckDB SQL. This playground uses the full exported GLF demo dataset. Oracle-specific functions such as SYSDATE or DUAL may need a small DuckDB equivalent, but glf.table schema references are supported.

Built for learning

A real SQL engine, without the setup.

DuckDB-Wasm executes the query inside your browser. The full exported GLF demo database is recreated in DuckDB-Wasm when the page loads. You can practice against the same tables and data used to build the SQL tutorials, without changing anything on a server.

V2 READY

Designed for a future database backend

The editor talks to a separate execution layer. Later, glFlow can replace the browser engine with an API-backed database while keeping the same playground interface.
