Appendix A. PostgreSQL 錯誤代碼 · PostgreSQL 中文文檔 9.3

# Appendix A. PostgreSQL 錯誤代碼 PostgreSQL服務器發出的所有消息都賦予了五個字符的錯誤代碼，這些代碼遵循 SQL 的"SQLSTATE"代碼的習慣。需要知道發生了什么錯誤條件的應用通常應該測試錯誤代碼，而不是查看文本錯誤信息。這些錯誤代碼輕易不會隨著PostgreSQL的版本更新而修改，并且一般也不會隨著錯誤信息的本地化而發生修改。請注意有些(但不是全部) PostgreSQL生成的錯誤代碼是由 SQL 標準定義的；有些標準沒有定義的錯誤條件是發明的或者是從其它數據庫借來的。根據標準，錯誤代碼的頭兩個字符表示錯誤類別，而后三個字符表示在該類別內特定的條件。因此，那些不能識別特定錯誤代碼的應用仍然可以從錯誤類別中推斷要做什么。 [Table A-1](#calibre_link-1092)里面列出了PostgreSQL 9.3.1 定義的所有錯誤代碼(有些實際上目前并沒有使用，但是 SQL 標準定義了)。錯誤類別也列出在此。對于每個錯誤類別都有個"標準"的錯誤代碼，它的最后三個字符是`000`。這個代碼只用于那些落在該類別內，但是沒有賦予任何更準確的代碼的錯誤條件。 "條件名"列顯示的標志是在PL/pgSQL里面使用的條件名。條件名大小寫無關。（請注意PL/pgSQL并不識別警告，這一點和錯誤、條件名正相反；那些是 00，01，02 類別。）對于某些類型的錯誤，服務器報告與錯誤相關的數據庫對象的名稱（一個表，表字段，數據類型，或者常量）；例如，唯一約束的名字導致了一個`unique_violation`錯誤。類似的名字在單獨的錯誤報告字段信息中提供，這樣應用程序就不用嘗試去從可能的本地化人可讀的信息文本中提取它們。自PostgreSQL 9.3起，對這個信息的完全覆蓋只存在于SQLSTATE類23的錯誤中（完整性約束違反），但這個可能在將來擴展。 **Table A-1\.
