42000 — 语法错误或访问规则违反

速览 {#at-a-glance}

SQLSTATE 42000 是 Class 42 中的 syntax_error_or_access_rule_violation。42000 是“语法错误或访问规则违反”的宽泛总类。本批固定 PostgreSQL 路径报告 42501、42601 等具体子码，因此只记录定义边界。

含义 {#meaning}

42000 是“语法错误或访问规则违反”的宽泛总类。本批固定 PostgreSQL 路径报告 42501、42601 等具体子码，因此只记录定义边界。

诊断 {#diagnosis}

先按服务器 SQLSTATE 和命令阶段分类。客户端解析异常或本地抛出的异常不能证明总类码，也不要把具体子码扩大记录为 42000。

处理 {#response}

按诊断中指出的具体语法或访问规则修复并重试该命令，在日志和指标中保留子码。

报文 {#messages}

本页没有选定的自然 producer，也没有为该总类确认固定子报文。本批具体后端路径报告的是 42501、42601 等子 SQLSTATE；只有客户端异常而没有服务器 SQLSTATE 时，不能据此认定 42000。

代表案例 {#case}

本页没有选定的自然 SQL 运行；这里只记录固定源码边界，不使用伪造触发器。

版本 {#versions}

本页没有选定的自然 SQL 运行；固定的 REL_18_6/REL_10_23 源码边界不能证明所有中间版本的行为。
