name: Backend Queries description: Write efficient, secure database queries using parameterized queries, eager loading, and performance optimizations. Use this skill when writing database queries, implementing data retrieval logic, using ORM query builders, writing raw SQL queries, implementing eager loading or joins, preventing N+1 query problems, implementing query filters or search functionality, using transactions for data consistency, implementing pagination queries, optimizing slow queries, implementing query caching, working with query builder methods, or writing repository/DAO layer code. Use when working with SQL queries, ORM query builders like Sequelize, TypeORM, Prisma, SQLAlchemy, ActiveRecord, Django ORM query APIs, or raw database access code.

When to use this skill

• When writing database queries using ORM query builders
• When writing raw SQL queries
• When implementing data retrieval or search logic
• When implementing eager loading or joins to prevent N+1 queries
• When optimizing slow or inefficient queries
• When implementing query filters, sorting, or pagination
• When using transactions to ensure data consistency
• When implementing query caching for expensive queries
• When working with query builder methods (where, select, join, etc.)
• When writing repository, service, or DAO layer code
• When preventing SQL injection with parameterized queries
• When working with complex queries involving multiple tables
• When implementing query timeouts or performance monitoring
• When working with ORMs like Sequelize, TypeORM, Prisma, SQLAlchemy, ActiveRecord, Django ORM
