/*
比较两数据库的结构;
参数如下:
exec r_pro_xx
@oldserver='ma',--老的数据库的连接信息
@olddb ='olddb',
@olduser='sa',
@oldpw='a',
@newserver ='ma',--新的
@newdb='newdb',
@newuser='sa',
@newpw ='a',
@comtype ='p'--‘p’是比较的存储过程，‘u’是比较的表
注意:现在仅对表和存储过程进行比较,而且存储过程的比较还有缺陷,
缺陷如下:
如果两表中的同一存储过程,仅仅是空格或开始位置不一样,它也认为是不一样的..如何处理?
嘿嘿.
如果哪位有兴趣,帮改改哈.改完后联系我.
