Frequently Asked Questions

Which SQL dialects are supported?

PostgreSQL, MySQL, and SQLite. Switch the dialect using the toolbar dropdown before generating.

How are nested JSON objects handled in SQL output?

Nested objects are serialized as JSON strings in a TEXT column. Flat relational structures produce the cleanest SQL output.

Are string values properly SQL-escaped?

Yes. Single quotes in string values are escaped to prevent SQL injection-style syntax errors.
