40002 — transaction_integrity_constraint_violation(事务完整性约束违规)
速览 {#at-a-glance}
40002 是目录定义的事务完整性条件。本批固定扫描没有解析出独立的 PostgreSQL 核心 40002 抛出点,因此不把外键、唯一性或其他具体约束错误重新标成这个总括码。应保存操作实际发出的 SQLSTATE。
含义 {#meaning}
40002 表示 40 类的事务完整性约束违规,但固定的 PostgreSQL 核心扫描没有解析出独立的 40002 调用点。PostgreSQL 的具体完整性机制通常报告 23 类具体码,例如 23502、23503、23505、23514 或 23P01。
诊断 {#diagnosis}
从错误中读取实际 SQLSTATE、约束名、关系、列和 DETAIL。服务器给出具体 23 类码时,应按该约束及事务状态诊断;不能因为操作发生在事务中就升级为 40002。本页没有选定的自然运行案例,也没有服务器特定报文模板。
处理 {#response}
修复具体约束违规和事务边界,再核对预期持久化状态。不要添加通用重试,也不要把已知 235xx/23P01 结果改称 40002;只有真实组件提供该码及其证据时才使用这一类定义。
版本 {#versions}
上面的锁定事实表记录项目快照范围内的目录存在情况。固定源码证据只覆盖下面声明的路径;不能仅从定义推导精确行为引入版本或更广的运行覆盖。
相关 {#related}
服务器给出具体完整性码时,应使用它,例如23503 外键违规或23505 唯一性违规。
