<100分求解>SQL SEREVR存储过程解密的问题
现有一个存储过程需要解密.请各位大大帮忙.
我看了一些文章.大多都是用这个存储过来来解密. exec sp_decrypt (@XXXXXX)
他输出的文件是在什么地方?还是直接对原文件进行破解?
有一个SQL解密器 V6.0的比较好,但是没注册只能解前1000个字符，请哪位大大发一个注册机给我谢谢了Email:yzj520hyy@126.com

2000版的 j9988的最好

===============
把上面的代码生成一个存储过程，然后调用就可以了，输出的结果就是解密后的内容，对于 SQL2000百分之百有效
调用格式：
exec sp_xjj '解密存储过程名 '
