[解决办法]
看看这一帖?
http://topic.csdn.net/u/20080203/10/5c8b6ffe-a7d2-44cc-9597-ed5a6c0d0d8e.html
不过貌似就是小枪贴的那个,
注意一下登录方式.
[解决办法]
可以从数据库里面把这个加密的东西导出来吧？
记得2000里面有个字段用来存储这个存储过程的内容，现在2005不知道改成什么了。
[解决办法]
视乎2005还不可以解密
[解决办法]
那么解密的过程要用dac登录才能正常运行

   目前这个存储过程只能解密存储过程，

   至于解密函数、触发器、视图的存储过程本网站会进一步关注，调用形式为：

   exec dbo.sp__windbi$decrypt @procedure,0

   如果第二个参数使用的话，会给出该存储过程的一些提示。

   --版本.0  修正存储过程过长引起的问题


   警告：该存储过程会删除并重建原始的存储过程。'

         在运行该存储过程之前确保你的数据库有一个备份。'

         该存储过程通常应该运行在产品环境的一个备份的非产品环境下。
