Oracle中如何恢复被删掉的存储过程?

在某些时候,容易误删存储过程,那么针对存储过程被删除了,我们如何进行恢复呢 ? 这里为大家进行讲解。

1.  创建测试存储过程
SQL> conn roger/roger
Connected.
SQL> CREATE OR REPLACE PROCEDURE proc_test_drop
  2  AS
  3  BEGIN
  4     FOR x IN (SELECT sysdate FROM dual)
  5     LOOP
  6        DBMS_OUTPUT.put_line (x.sysdate);
  7     END LOOP;
  8  END proc_test_drop;
  9  /

Procedure created.

SQL> set serveroutput on
SQL> exec proc_test_drop;

PL/SQL procedure successfully completed.

SQL>

SQL> l
  1* select text,name from dba_source where owner='ROGER' and name='PROC_TEST_DROP'
SQL> /

TEXT                                              NAME
------------------------------------------------- ------------------------------
PROCEDURE proc_test_drop                          PROC_TEST_DROP
AS                                                PROC_TEST_DROP
BEGIN                                             PROC_TEST_DROP
   FOR x IN (SELECT sysdate FROM dual)            PROC_TEST_DROP
   LOOP                                           PROC_TEST_DROP
      DBMS_OUTPUT.put_line (x.sysdate);           PROC_TEST_DROP
   END LOOP;                                      PROC_TEST_DROP
END proc_test_drop;                               PROC_TEST_DROP

8 rows selected.

SQL> show user
USER is "SYS"
SQL> conn roger/roger
Connected.
SQL> drop PROCEDURE proc_test_drop;

Procedure dropped.

SQL> select text,name from dba_source where owner='ROGER' and name='PROC_TEST_DROP';
