本来想发帖居然没有20分我靠  我要在所有百万级分页中都用这个回复declare @d datetime;set @d=getdate()

当然我的电脑绝对是淘汰货 Pentium Dual-Core Cpu E5500 2.80GHZ 2.79GHZ 1.96的内存至于为什么是通用的你没发现这个语句是有规律的吗！你只要发挥一下你的聪明才智用存储过程也行
用程序拼接字符串也行当然我也想获取各位大神的通用的sqlserver 2000的分页方法如果有更好更通用的方法请各位大神发下
（模拟数据库就不发了本人比较懒惰想测试的自己设置一下模拟环境吧）
构造分页的通用方法主要代码  你可以尽量完善这个方法
