Dynamic queries: separate values from structure choices

Flexible filters need a bounded contract.

AppSec

Content produced with AI assistance for Thiago Silva’s website. Independent editorial analysis; it does not represent clients or employers.

Reading context

A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.

The architecture decision

Reporting APIs can accumulate combinations that are hard to review. Distinguish user-supplied values from choices changing query structure.

Practical application

Editorial proposal: make supported fields, ordering and operators part of the product contract. For a hypothetical report, turn actual needs into explicit options rather than an improvised query language.

How to verify

Test valid, unknown and excessive combinations. Explain rejections before database execution. Alongside security, this improves cost predictability and maintenance as reporting grows.
