存储过程被加密了,如何查看??
我把服务器上的数据库下载到本地,发现被加密的存储过程没有下载下来,直接在链接到服务器查看提示“Encrypted object is not transferable, and script can not be generated. ”
请问这么处理?
在网上搜索了一下,发现有一些解密代码,这个解密代码怎么使用??
我放在查询分析器里运行了一下,提示命令完成,然后再去看存储过程,还是一样的提示??
请帮忙解答一下,非常感谢!!

exec sp_decrypt '存储过程名 '

--楼上说得对,不过sp_decrypt又不是SQL Server自带的,
--网上流传多个版本,现在把我使用的帖上来,在SQL server 2000中用了很多次没发现有问题
CREATE PROCEDURE sp_decrypt(@objectName varchar(50))
