Oracle
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:
