An opinionated style guide for writing clean, readable, and maintainable SQL, authored by a data analyst. It documents formatting conventions such as lowercase keywords, CTE usage, and column alignment with annotated examples.

Use cases

• adopt a sql formatting standard for my analytics team
• learn how to write clean readable sql queries
• find best practices for formatting ctes and joins
• set up a sql style guide for my company
• review sql code style conventions
• improve maintainability of sql in dbt or looker projects

When to choose

• you or your team lack a SQL style guide and want a well-explained starting point
• you want opinionated, example-driven formatting conventions you can adapt
• you are a data analyst or analytics engineer standardizing query style

When to avoid

• your team already follows a different established SQL style (e.g., dbt Labs or GitLab guides)
• you need an automated formatter or linter rather than a written guide
• you need dialect-specific SQL standards beyond general formatting
