Backend Queries

使用参数化查询、急载、正确索引和事务管理，编写安全、高效和优化的数据库查询。在控制器、存储库、服务或模型方法中编写数据库查询时使用此技能，当使用查询构建器或ORM方法、实现过滤/排序/分页逻辑、用急载优化N+1查询问题、处理连接和复杂查询、实现查询缓存，或在数据库事务中包装相关操作时使用。

name: Backend Queries
description: Write secure, performant, and optimized database queries using parameterized queries, eager loading, proper indexing, and transaction management. Use this skill when writing database queries in controllers, repositories, services, or model methods, when using query builders or ORM methods, when implementing filtering/sorting/pagination logic, when optimizing N+1 query problems with eager loading, when working with joins and complex queries, when implementing query caching, or when wrapping related operations in database transactions.

Backend Queries

This Skill provides Claude Code with specific guidance on how to adhere to coding standards as they relate to how it should handle backend queries.

When to use this skill

  • •When writing database queries in controllers, service classes, repositories, or model methods
  • •When using query builder methods (where, select, join, orderBy, etc.)
  • •When implementing eager loading to prevent N+1 query problems (with, load, etc.)
  • •When optimizing queries by selecting only needed columns instead of using SELECT *
  • •When implementing filtering, sorting, or pagination logic in queries
  • •When writing complex queries with joins, subqueries, or aggregations
  • •When wrapping multiple related database operations in transactions
  • •When implementing query timeouts or performance optimization
  • •When adding database indexes to improve query performance
  • •When implementing query result caching strategies
  • •When using raw queries or complex SQL (ensuring parameterization for security)
  • •When debugging slow queries or performance issues
