Should I format SQL before committing to version control?

Yes. Consistently formatted SQL makes code reviews easier and reduces merge conflicts. Use a formatter in a pre-commit hook or CI pipeline.

Is it safe to paste production SQL into online formatters?

Only with client-side tools like DevToolHQ. SQL queries can reveal table names, column names, and business logic. Server-side formatters like SQLFormat.org process your query on their servers.

What is the best SQL style — uppercase or lowercase keywords?

Uppercase keywords (SELECT, FROM, WHERE) is the most common convention and improves readability by visually separating SQL keywords from table and column names.
