database-interaction-best-practices

database-interaction-best-practices is a cursor rule for Cursor from holtwood/awesome-cursorrules-zh. It costs 89 tokens per session, scanned A, original, MIT.

Guidance for connecting Go backend code to a database, including safe queries, error handling, connection reuse, and optional use of an object-relational mapper, a tool that maps code objects to database data.

In plain words
What is it for?
Use it when writing database queries, managing connections and connection pools, handling database errors, or modeling complex data.
Why use it?
It helps avoid SQL injection, leaked connections, weak error handling, and inefficient database access.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

database-interaction-best-practices scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

与数据库交互时:

  • 使用预处理语句以防止 SQL 注入。
  • 优雅地处理数据库错误。
  • 考虑使用 ORM 进行复杂的查询和数据建模。
  • 在不再需要时关闭数据库连接。
  • 使用连接池以提高性能。
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
