Postgresql 中文操作指南
Appendix A. PostgreSQL Error Codes
PostgreSQL 服务器发出的所有消息都被分配了五个字符的错误代码,该代码遵循 SQL 标准的“SQLSTATE”代码约定。需要了解已发生的错误条件的应用程序通常应测试错误代码,而不是查看文本错误消息。错误代码在 PostgreSQL 发布之间不太可能更改,并且也不会因错误消息的本地化而发生更改。请注意,PostgreSQL 生成的错误代码中并非全部,但有一部分是由 SQL 标准定义的,一些其他错误代码是为非标准定义的条件而创建或从其他数据库中借用的。
根据该标准,错误代码的前两个字符表示一类错误,而后三个字符表示该类中的特定条件。因此,不识别特定错误代码的应用程序仍然可以从错误类中推断出该怎么做。
Table A.1 列出了 PostgreSQL 16.3 中定义的所有错误代码。(有些目前实际上并未使用,但由 SQL 标准定义。)错误类也显示在其中。对于每个错误类,都有一个“标准”错误代码,其后三个字符为 000 。此代码仅用于属于该类但未分配任何更具体代码的错误条件。
“Condition Name”列中显示的符号是 PL/pgSQL 中使用的条件名称。条件名称可以大写或小写书写。(请注意,PL/pgSQL 无法识别警告,而不是错误,条件名称,它们是类 00、01 和 02。)
对于某些类型的错误,服务器报告与该错误相关联的数据库对象(表、表列、数据类型或约束)的名称,例如导致 unique_violation 错误的唯一约束的名称。此类名称在错误报告消息的单独字段中提供,以便应用程序不必尝试从可能本地化的人类可读消息文本中提取这些名称。从 PostgreSQL 9.3 开始,此功能的完整覆盖范围仅存在于 SQLSTATE 类 23(完整性约束违反)中的错误,但这可能会在未来得到扩展。
