plsql - oracle 11g 带触发器的存储过程

Question

我有一个由 4 个不同的触发器调用的存储过程是否可以在执行过程时获取触发器的信息，例如名称。

我可以通过向程序传递一个额外的参数来做到这一点，还有其他选择吗？我正在使用 oracle 11g。谢谢

Answer 1

您可以使用此处dbms_utility.format_call_stack记录的功能：

SQL> set serveroutput on
SQL> create table test_table (n number);

Table created.

SQL> create or replace procedure test_procedure as
  2  begin
  3     dbms_output.put_line(dbms_utility.format_call_stack);
  4  end;
  5  /

Procedure created.

SQL> create or replace trigger test_trigger_insert
  2  before insert on test_table
  3  for each row
  4  begin
  5     test_procedure;
  6  end;
  7  /

Trigger created.

SQL> create or replace trigger test_trigger_delete
  2  before delete on test_table
  3  for each row
  4  begin
  5     test_procedure;
  6  end;
  7  /

Trigger created.

SQL> rem direct execution of the procedure
SQL> exec test_procedure;
----- PL/SQL Call Stack -----
  object      line  object
  handle    number  name
0x2bc2f1ca0         3  procedure YOUR_SCHEMA.TEST_PROCEDURE
0x31a218568         1
anonymous block


PL/SQL procedure successfully completed.

SQL> rem procedure called by trigger test_trigger_insert
SQL> insert into test_table (n) values (42);
----- PL/SQL Call Stack -----
  object      line  object
  handle    number  name
0x2bc2f1ca0         3  procedure YOUR_SCHEMA.TEST_PROCEDURE
0x2adc40fb0         2
YOUR_SCHEMA.TEST_TRIGGER_INSERT


1 row created.

SQL> rem procedure called by trigger test_trigger_delete
SQL> delete from test_table where n = 42;
----- PL/SQL Call Stack -----
  object      line  object
  handle    number  name
0x2bc2f1ca0         3  procedure YOUR_SCHEMA.TEST_PROCEDURE
0x2f10ffd28         2
YOUR_SCHEMA.TEST_TRIGGER_DELETE


1 row deleted.

如果您的触发器名为 My_Trigger 您可以尝试以下操作：

SELECT Trigger_type, Triggering_event, Table_name
   FROM USER_TRIGGERS
   WHERE Trigger_name = 'My_Trigger';
