SnIPPETsX › Online SQL compiler. Queries without a database server

Online SQL compiler. Queries without a database server.

Free online SQL compiler. Create tables, insert rows and run SQL queries in your browser on a SQLite engine, then share the query by link. No database setup.

CREATE, INSERT, SELECT — run a whole SQL script in a throwaway SQLite database.

The short answer

SnIPPETsX is a free online SQL compiler. Choose SQL, write a script that creates tables, inserts rows and runs queries, and press Run. It executes against a fresh SQLite database in an isolated sandbox and prints the query results. No database server, install or account is needed, and the script is shareable by URL.

Each run starts with a fresh, empty SQLite database.
Put CREATE TABLE and INSERT statements in the same script as your queries.

Practise and share SQL without installing a database

Learning SQL or answering an SQL interview question should not require installing MySQL or PostgreSQL. SnIPPETsX runs your whole script — schema, sample data and queries — against a throwaway SQLite database and shows the result.

Because each run starts empty, the script itself is the full reproduction. Share the link and anyone can see the schema, the data and the query, run it, and suggest a fix live. That makes it a clean way to ask for help with a JOIN, a GROUP BY or a window function.

Frequently asked questions

Which SQL dialect does the online SQL compiler use?

SQLite. Standard SELECT, JOIN, GROUP BY, subqueries and common table expressions work; MySQL- or PostgreSQL-specific functions may not.

Does my data persist between runs?

No. Every run starts with an empty database, so include CREATE TABLE and INSERT statements in the script.
