Frequently Asked Questions

Dialect?

Mostly ANSI. Handles common PostgreSQL/MySQL/SQLite clauses.

Strings?

Single- and double-quoted string literals are preserved verbatim. Dollar-quoted bodies ($$…$$) are not tokenized specially, so their contents may be reflowed.

How do I use the SQL Viewer?

Just type your numbers. The answer shows up right away — there is no button to press. Change anything and it updates by itself.

Do I need to install or sign up for anything?

Not at all — it runs in the browser with nothing to install and no account. After it loads once, it even works without an internet connection.

Is my information private?

Yes. Everything happens in your browser. Nothing you type is sent to a server or saved anywhere.
