# 附录 A. PostgreSQL 错误代码

PostgreSQL服务器发出的所有消息都分配了五个字符的错误代码， 这些代码遵循 SQL 的"SQLSTATE"代码的约定。 需要知道发生了什么错误条件的应用程序通常应该检测错误代码，而不是查看文本错误消息。 这些错误代码不太可能随着PostgreSQL的版本的更新而修改， 并且一般也不会随着错误消息的本地化而发生修改。请注意有些(但不是全部) PostgreSQL生成的错误代码是由 SQL 标准定义的； 有些标准里并没有定义的错误条件会被发明或者是从其它数据库借过来。

根据标准，错误代码的头两个字符表示错误类别，而后三个字符表示在该类别内特定的条件。 因此，那些不能识别特定错误代码的应用仍然可以从错误类别中推断要做什么。

表 A-1里面列出了PostgreSQL 9.4.4 定义的所有错误代码(有些实际上目前并没有使用，但是 SQL 标准定义了)。错误类别也列出在此。 对于每个错误类别都有个"标准"的错误代码，它的最后三个字符是`000`。 这种代码只用于那些落在该类别内，但是没有赋予任何更准确的代码的错误条件。

"条件名"列显示的标志是在PL/pgSQL里面使用的条件名。 条件名大小写无关。（请注意PL/pgSQL并不识别警告， 这一点和错误、条件名正相反；那些是 00，01，02 类别。）

对于某些类型的错误，服务器报告与错误相关的数据库对象的名称（一个表，表字段，数据类型， 或者约束）；例如，唯一约束的名字导致了一个`unique_violation`错误。 类似的名字在单独的错误报告字段信息中提供， 这样应用程序就不用尝试去从可本地化 可读的文本消息中提取它们。 自PostgreSQL 9.3起，对这个特性的完全覆盖只存在于SQLSTATE类23的错误中（违反完整性约束）， 但这个将来可能会被扩展。
