实用的备份PL/SQL程序工具

MILY: 黑体; mso-hansi-font-family: 宋体">/*ligang1000@hotmail.com*/

功能: 用于备份当前用户所拥有的所有PL/SQL objects (包括

TYPE,TYPE BODY, PROCEDURE , FUNCTION, PACKAGE, PACKAGE BODY or JAVA SOURCE )

原理: 对USER_SOURCE数据字典的调用,得到所有的

PL/SQL 代码.

使用方法举例:

1.     在C盘建立目录C:\EXPORT

2.     将EXPORT_SOURCE.SQL和EXTRACT_SOURCE.SQL拷贝到C盘根目录.

3.     登陆SQLPLUS , CONNECT SCOTT/TIGER

4.     运行@C:\EXPORT_SOURCE.SQL

5.     执行结束,所有的SCOTT拥有的PL/SQL object的代码文件建立在C:\EXPORT目录里．

后缀名.PKS 表示PACKAGE

后缀名.PKB 表示PACKAGE BODY

后缀名.SQL 表示其他OBJECTS

备注：

如果想得到数据库中各个SCHEMA的PL/SQL objects ,只需把工具代码中的USER_SOURCE改成DBA_SOURCE,由SYSTEM

运行即可.

工具代码：

export_source.sql
