如何在跟踪文件中獲取語法和邏輯 ORA？

有一個包含大量查詢的應用程序，其中一個導致 ORA-1722

檢查：我打開會話跟踪，如：

alter session set events '10046 trace name context forever, level 12'

並對數據庫說

SELECT TO_NUMBER('asdf') FROM DUAL;

我實際上在客戶端收到 ORA-1722，但看不到該查詢以錯誤程式碼完成：

如何檢測導致 ORA-1722（或任何其他邏輯/語法問題）的查詢？

您可以跟踪特定錯誤，如下所示：

SQL> alter session set events '1722 trace name errorstack level 1';

Session altered.

SQL> SELECT TO_NUMBER('asdf') from dual;
SELECT TO_NUMBER('asdf') from dual
                *
ERROR at line 1:
ORA-01722: invalid number

在跟踪文件中：

要記錄它們，您可以使用 servererror 觸發器，如下所示：

在 Oracle 中是否可以跟踪導致錯誤的 SQL 語句？
