Does it follow specific formatting standards?

Yes, it is designed to be compatible with SQLFluff, enforcing trailing commas, uppercase keywords, and explicit JOIN declarations for cleaner diffs and code reviews.

How does this skill improve query performance?

It implements 'filter early' strategies, encourages the use of EXPLAIN ANALYZE for profiling, and suggests efficient window functions and aggregation patterns.

Can it help with database schema migrations?

Absolutely. It includes standardized patterns for creating tables, indexes, and enums, ensuring your schema is robust and follows modern database design principles.

Does this skill support specific SQL dialects?

Yes, it provides tailored guidance and optimization patterns specifically for PostgreSQL and BigQuery, while adhering to general ANSI SQL best practices.

Why does it emphasize CTEs over subqueries?

CTEs (Common Table Expressions) improve readability and maintainability by breaking complex logic into named, logical steps that are easier to debug and test.
