FAQ
?Which SQL dialects are supported?
We currently support standard SQL, PostgreSQL, MySQL, SQLite, and T-SQL (SQL Server).
?Is my database data secure?
Absolutely. All formatting logic is executed on your local machine using JavaScript. We never transmit or store your queries, schemas, or data.
?Does it validate SQL syntax?
Yes, it provides basic syntax validation. If your query is severely malformed, an error indicator will help you identify the problematic area.
