Core SQL Formatting Conventions
1. Uppercase Keywords: Reserving uppercase letters for reserved SQL commands (SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING) creates a clear visual hierarchy separating logic from table and column names.
2. Indented Clauses: Indenting conditional filters beneath WHERE clauses and each JOIN statement allows developers to instantly grasp data relationships and filtering rules.
3. Comma Placement: Grouping selected column projections on individual lines makes git pull request diffs clean and prevents accidental omissions.
Why Schema Privacy Matters When Formatting SQL
Database queries frequently contain internal table schema names, proprietary column definitions, and sensitive customer data within WHERE conditions.
Sending your proprietary SQL to cloud-based formatters exposes your database schema to external logging. DocSwift parses SQL tokens strictly within your browser's local JavaScript engine, safeguarding your proprietary database models.
