How it works

This is a rule-based formatter, not a full SQL parser — it handles common SELECT/INSERT/UPDATE/DELETE patterns well but may not perfectly format deeply nested subqueries.
Leading commas put the comma at the start of each line rather than the end — a style many teams prefer because it makes it easy to comment out a column without breaking the syntax.
The stats show how many tables and joins your query touches — a quick sanity check when reviewing someone else's SQL.
