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;

  06-AUG-13

  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';

  no rows selected

  SQL>

  —-利用闪回查询进行恢复

  CREATE OR REPLACE FORCE VIEW “SYS”.”DBA_SOURCE” (“OWNER”, “NAME”, “TYPE”, “LINE”, “TEXT”) AS

  select u.name, o.name,

  decode(o.type#, 7, ‘PROCEDURE’, 8, ‘FUNCTION’, 9, ‘PACKAGE’,

  11, ‘PACKAGE BODY’, 12, ‘TRIGGER’, 13, ‘TYPE’, 14, ‘TYPE BODY’,

  ‘UNDEFINED’),

  from sys.obj$ o, sys.source$ s, sys.user$ u

  where o.obj# = s.obj#

  and o.owner# = u.user#

  and ( o.type# in (7, 8, 9, 11, 12, 14) OR

  ( o.type# = 13 AND o.subname is null))

  union all

  select /*+ ordered */ distinct u.name, o.name, ‘JAVA SOURCE’, s.joxftlno, s.joxf

  and o.type# = 28

  SQL> conn /as sysdba

  Connected.

  SQL> select text from dba_source as of timestamp sysdate-5/60/24 where owner='ROGER' and name='PROC_TEST_DROP';

  TEXT

  LOOP

  DBMS_OUTPUT.put_line (x.sysdate);

  END LOOP;

  END proc_test_drop;

  8 rows selected.

  —-通过基表进行恢复

  SQL> alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss';

  Session altered.

  SQL> select sysdate from dual;

  SYSDATE

  -------------------

  2013-08-06 02:46:21

  SQL> select obj# from obj$ as of timestamp to_timestamp('2013-08-06 02:40:00', 'YYYY-MM-DD HH24:MI:SS') where name='PROC_TEST_DROP';

  OBJ#

  SQL> set long 9999999

  SQL> select source

  2 from source$ as of timestamp to_timestamp('2013-08-06 02:40:00', 'YYYY-MM-DD HH24:MI:SS')

  3 where obj# = 52148

  4 order by line;

  SOURCE

  PROCEDURE proc_test_drop

  BEGIN

  FOR x IN (SELECT sysdate FROM dual)

  LOOP

  DBMS_OUTPUT.put_line (x.sysdate);

  END LOOP;

  END proc_test_drop;

  ++++利用odu等工具进行恢复

  SYS_SOURCE$.sql:

  CREATE TABLE “SYS”.”SOURCE$”

  (

  “OBJ#” NUMBER NOT NULL,

  “LINE” NUMBER NOT NULL,

  “SOURCE” VARCHAR2(4000)

  );

  SYS_SOURCE$.ctl:

  –

  –Generated by ODU,for table “SYS”.”SOURCE$”

  –

  OPTIONS(BINDSIZE=8388608,READSIZE=8388608,ERRORS=-1,ROWS=50000)

  LOAD DATA

  INFILE ‘SYS_SOURCE$.txt’ “STR X’0a’”

  APPEND INTO TABLE “SYS”.”SOURCE$”

  FIELDS TERMINATED BY X’7c’ TRAILING NULLCOLS

  (

  “OBJ#” ,

  “LINE” ,

  “SOURCE” CHAR(4000)

  )

  更改owner,然后将数据加载到roger用户中.
