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.
