图老师小编精心整理的oracle 存储过程加密的方法希望大家喜欢，觉得好的亲们记得收藏起来哦！您的支持就是小编更新的动力~
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

Processing a.sql to a.plb
4.打开a.plb，现在它的内容如下：
Java代码
create or replace procedure test1 wrapped

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
