02001 — no_additional_dynamic_result_sets_returned
速览 {#at-a-glance}
02001 是关于额外动态结果集的无数据类条件，不是普通查询无行。没有解析出 18.6 核心与 contrib 报告组。
含义 {#meaning}
定义名称表示额外动态结果集已经耗尽，但固定源码扫描没有确认实现路径。
消息与诊断 {#messages}
没有解析出 18.6 消息变体。应保留产生它的过程/接口、结果集位置、客户端 API 和完整诊断。
诊断 {#diagnosis}
定位产生该代码的动态结果集契约，并确认调用方是否确实请求了下一个结果集。不要用普通行数检查或 PL/pgSQL NO_DATA_FOUND 处理替代它。
处理 {#response}
按实际接口处理结果集序列结束，或修正调用方期待的数量。不变的事务重试不会产生另一个结果集。
版本 {#versions}
02001 在锁定目录 9.0.23 至 18.6 以及 19 Beta 3 中存在，known_present_by 为 7.4。对固定 18.6 扫描而言，这只是定义证据。
相关 {#related}
0100C 涉及动态结果集返回；P0002 是 PL/pgSQL no-data-found；02000 是一般无数据条件。
