To Learn Detail of Error Message

Question

Hi All;
We have an executable that i can not debug or reach code, somehow a blackbox. When i execute it, i only get 942 error as i simulated below:
SQL> SELECT * FROM no_existed_or_granted_table;
SELECT * FROM no_existed_or_granted_table
ORA-00942: table or view does not exist
SQL> I only get ORA-00942: table or view does not exist message with output.
Is it possible to know which table or view gets this error?
Thanks & Regards..

Answer 1

Yes it should work:
SQL> CREATE TABLE error_tab (error_date DATE, error_msg VARCHAR2(512), SQL VARCHAR2(4000))
Table created.
SQL> CREATE OR REPLACE TRIGGER my_after_server_error_trg
   AFTER SERVERERROR ON DATABASE
DECLARE
   p_sql_text   ora_name_list_t;
   p_stmt       VARCHAR2 (4000);
BEGIN
   FOR i IN 1 .. ora_sql_txt (p_sql_text)
   LOOP
      p_stmt := p_stmt || p_sql_text (i);
   END LOOP;
   INSERT INTO error_tab
        VALUES (SYSDATE,
                ora_server_error_msg (1),
                p_stmt
END my_after_server_error_trg;
Trigger created.
