SQL Playground

About the tool

The Structured Query Language (SQL) is a language used to manage data held in relational databases.

This tool allows you to create a relational database and query it entirely in the browser using SQL.

The tool uses the sql.js library (a WASM port of the SQLite database engine) and provides a SQL query editor with syntax highlighting for creating and querying tables.

The database does not persist data between sessions or send it to the server.

Demo
