v3.5.0: 请评估 docs/query-builder-guide.md 选择合适方案。标准 CRUD 推荐迁移到 sz_orm_core::QueryBuilder<M>

查询构造器入口

§渐进 Deprecation 说明(v3.5.0)

自 v3.5.0 起,sz-orm-query-builder 进入渐进 deprecation 阶段。 请评估 docs/query-builder-guide.md 选择合适方案:

  • 标准 CRUD:推荐迁移到 sz_orm_core::QueryBuilder<M>(编译期类型安全)
  • 复杂 SQL(UNION/CTE/窗口函数):可继续使用本 crate(暂不删除)

本 crate 在 v3.5.0 不立即删除,API 完全兼容,仅添加 #[deprecated] 警告。 计划在 v4.0.0 评估是否合并到 sz-orm-core 或保留独立。
