oracle 备份数据库对象(存储过程PROCEDURE,FUNCTION,VIEW,TRIGGER...)

开发过程中,需要不停的备份数据库对象, 特别是存储过程, 每次手动备份不免很低能啊

历经几次修改终于, 完美了,O(∩_∩)O哈哈~      (当然,你也可以再改简便一点~~~)

select dbms_metadata.get_ddl('PROCEDURE',"PROCEDURE_NAME",'NAG') 遇到大存储过程老是丢东西不说, 对象名 还老是 "用户名"."对象名" 的格式,腻烦人!~

CREATE OR REPLACE PROCEDURE OBJAUTOSTORE
AS
/* 功能：备份存储过程和视图
准备工作：
--1.创建文件夹 ：'D:/OracleBackUp/ProcBack';--文本存放的路径
--2.执行：create or replace directory MyProcBakPath as 'D:/OracleBackUp/ProcBack';
--3.赋权限：
sqlplus /nolog
conn nag/nag as sysdba
grant select on DBA_OBJECTS to NAG;
--4.创建Job，自动执行，自动备份存储过程
+缩减代码,归类循环执行 lzpong 2015/03/18
+更改代码,使超大存储过程也能保存,并且 不会出现 "用户名"."对象名" 的格式  lzpong 2015/07/14

　好了, 轻松了不少了吧~~
