SQL Optimization Patterns FAQs

Question 1

What does the SQL Optimization Patterns skill do?

Accepted Answer

This skill enables Claude Code to systematically analyze, debug, and rewrite slow SQL queries. It uses advanced techniques like EXPLAIN plan analysis, systematic indexing strategies, and query refactoring to transform slow database operations into high-performance queries.

Question 2

When should I use this skill?

Accepted Answer

You should activate this skill when debugging slow-running queries, designing performant database schemas, reducing database server costs, or scaling applications to handle larger datasets where performance has become a bottleneck.

Question 3

How does this skill improve my development workflow?

Accepted Answer

It automates the complex task of database performance tuning. Instead of manually parsing execution plans, Claude can instantly identify bottlenecks like full table scans (Seq Scans) and recommend precise fixes like composite indexes or cursor-based pagination.

Question 4

What specific optimization capabilities does it provide?

Accepted Answer

The skill provides guidance on EXPLAIN/ANALYZE interpretation, implementation of partial and covering indexes, elimination of N+1 query anti-patterns, efficient aggregation techniques, and advanced features like materialized views and table partitioning.

Question 5

Can it help fix performance issues caused by ORMs?

Accepted Answer

Yes, it is highly effective at identifying common ORM inefficiencies. It provides specific patterns to resolve N+1 query issues and helps refactor 'SELECT *' patterns into more efficient, column-specific queries that reduce I/O and memory usage.
