oracle 存储过程的加密方法小结
配置环境:
  1、数 据 库:Oracle 8i R2 (8.1.7) for NT 企业版
  2、安装路径:C:ORACLE
  实现方法:
  1.D:>set NLS_LANG=AMERICAN_AMERICA.USACII7
   或
   D:>set NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
D:>set
  直接打set命令可以查看环境变量
  2.在D:下创建a.sql文件,内容如下:
Java代码
  create or replace procedure test1(i in number) as
   begin
   dbms_output.put_line('输入参数是'||to_char(i));
   end;
  create or replace procedure test1(i in number) as
   begin
   dbms_output.put_line('输入参数是'||to_char(i));
   end;
  3.D:>wrap iname=a.sql
  PL/SQL Wrapper: Release 8.1.7.0.0 - Production on Tue Nov 27 22:26:48 2001

  5.运行a.plb
  Java代码
SQL> @d:a.plb
SQL> @d:a.plb
  过程已创建。
  6、运行存储过程
  Java代码
SQL> set serveroutput on
   SQL> execute test1(1);
SQL> set serveroutput on
   SQL> execute test1(1);
  输入参数是1
  PL/SQL 过程已成功完成。
  7、查看存储过程的代码
  Java代码
SQL> select name,text from all_source where type='PROCEDURE' and name='TEST1';
SQL> select name,text from all_source where type='PROCEDURE' and name='TEST1';
  结果:看不到其源码
