Question

我需要解压由其他开发人员创建的Oracle Package。我在我的数据库中创建了Prackage，但是采用加密格式。

我需要的原因是，原始开发人员离开了组织，现在包中的过程定义需要重新定义数据库结构和逻辑的更新更改。

有人可以帮助我，我怎么能在oracle中包装包。

Answer 1

您可以粘贴代码here，它会为您打开它请注意，您将丢失所有评论，但保留变量名称但是为了好玩，我们可以测试逻辑。

首先创建程序：

sqlplus testing/testtest
SQL*Plus: Release 11.2.0.3.0 Production on Fri Oct 10 08:36:06 2014
Copyright (c) 1982, 2011, Oracle.  All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> create or replace procedure AA as
  2  begin
  3  null;
  4  /*comments*/
  5  end;
  6  /
Procedure created.

接下来，我们将程序保存到操作系统中：

SQL> save aa.sql
Created file aa.sql
SQL> exit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
oracle@HOSTNAME:/home/oracle/USER/wrapTest> ll
total 12K
drwxr-x---. 4 oracle oinstall 4.0K Oct 10 08:36 ../
-rw-r-----. 1 oracle oinstall   66 Oct 10 08:37 aa.sql
drwxr-x---. 2 oracle oinstall 4.0K Oct 10 08:37 ./

保存后，我们将使用种子包装实用程序来混淆包：

oracle@HOSTNAME:/home/oracle/USER/wrapTest> wrap iname=aa.sql oname=aa.pls
PL/SQL Wrapper: Release 11.2.0.3.0- 64bit Production on Fri Oct 10 08:37:29 2014
Copyright (c) 1993, 2009, Oracle.  All rights reserved.
Processing aa.sql to aa.pls

现在让我们看看它的样子：

oracle@HOSTNAME:/home/oracle/USER/wrapTest> cat aa.
aa.pls  aa.sql
oracle@HOSTNAME:/home/oracle/USER/wrapTest> cat aa.pls
create or replace procedure AA wrapped
a000000

因此我们将该代码复制到该链接中，这就是它的样子：
unwrapped

正如您所看到的，我们丢失了评论但检索了代码。

所有包装是，是一个base64编码的凯撒加密压缩字符串。因此，如果您不想将代码粘贴到网站中：

Answer 3

如果您使用的是 SQL Developer，则可以从 Salvis 安装一个加载项 PL/SQL Unwrapper for SQL Developer 来解包 proc。参考https://github.com/Trivadis/plsql-unwrapper-sqldev

循序渐进：

打开 SQL Developer

帮助 > 检查更新，点击添加

设置名称=萨尔维斯位置=http://update.salvis.com/

然后 OK，然后检查 Salvis，然后 Next

让它添加和更新并重新启动 SQL Developer

重启后，找到一个被包裹的程序，在编辑器中打开右键单击编辑器，会出现新选项“解包”，单击它，您的 proc 应该是纯文本。

我们一直在努力解决 Oracle ASP.NET 成员资格提供程序 proc ora_aspnet_PPU_SetPgSettings 无法像 SQL Server 对应项那样工作的情况。解开它后，我们在那里发现了一个错误，我们得以修复。
