About this editor

SELECTs, JOINs, DDL on a live MySQL server. No mysql client install.

Practice SELECT, INSERT, UPDATE, JOINs, and CREATE TABLE against a live MySQL sandbox when you lack Workbench or the CLI on your machine. Useful for homework, cert prep, and validating a query before it hits staging. Save titled snippets to share MySQL playground examples with teammates.

Common questions

Is this MySQL compiler free?

Yes. No payment and no account required for a quick run. Sign in if you want saves tied to your profile.

Do I need to install anything?

No. Code runs on Codeground servers in a sandbox. Just open the page.

What MySQL version runs here?

MySQL in a sandbox.

Can I share my code?

Save with a title to get a permalink, or share the playground URL as-is.

Works for interviews?

Yes. Share a ground link, or use interview mode for a live shared editor.

Multiple files?

This page is for single-file snippets. Use a cloud workspace for full projects.

Will my code still be here tomorrow?

Anonymous sessions can reset. Save with a title (and sign in) for a stable link.

Why use this instead of installing locally?

Good for quick tests, learning, and sharing a snippet. For large offline work, a local IDE still wins.

Is this an online MySQL IDE or playground?

A browser playground with syntax highlighting and one-click Run — run MySQL online without a full local install. Cloud workspaces cover multi-file projects.

Create tables?

Yes, in the sandbox. Data may not stick around forever.

Is there a free MySQL playground?

Yes. Run MySQL SQL online for free—no local server install or cloud account for basic practice.

Is this a MySQL online IDE?

Browser SQL playground with editor and results—great for queries, not a full DBA admin suite.

Can I use MySQL online without installing MySQL?

Yes. The editor connects to a sandbox on our servers. You only need a browser—no mysql client download.
