oracle 備份數據庫對象(存儲過程PROCEDURE,FUNCTION,VIEW,TRIGGER...)

開發過程當中,須要不停的備份數據庫對象, 特別是存儲過程, 每次手動備份難免很低能啊

歷經幾回修改終於, 完美了,O(∩_∩)O哈哈~      (固然,你也能夠再改簡便一點~~~)

select dbms_metadata.get_ddl('PROCEDURE',"PROCEDURE_NAME",'NAG') 遇到大存儲過程總是丟東西不說, 對象名 還總是 "用戶名"."對象名" 的格式,膩煩人!~

CREATE OR REPLACE PROCEDURE OBJAUTOSTORE
AS
/* 功能：備份存儲過程和視圖
準備工做：
--1.建立文件夾 ：'D:/OracleBackUp/ProcBack';--文本存放的路徑
--2.執行：create or replace directory MyProcBakPath as 'D:/OracleBackUp/ProcBack';
--3.賦權限：
sqlplus /nolog
conn nag/nag as sysdba
grant select on DBA_OBJECTS to NAG;
--4.建立Job，自動執行，自動備份存儲過程
+縮減代碼,歸類循環執行 lzpong 2015/03/18
+更改代碼,使超大存儲過程也能保存,而且 不會出現 "用戶名"."對象名" 的格式  lzpong 2015/07/14

　好了, 輕鬆了很多了吧~~
