可以用存储过程来实现
if exists(select * from sysobjects where name='Proc_MyPagination')
drop procedure Proc_MyPagination
go
create procedure Proc_MyPagination
/*
***************************************************************
** 分页存储过程 **
***************************************************************
参数说明:
1.Tables :表名称,视图
2.PrimaryKey :主关键字
3.Sort :排序语句，不带Order By 比如：NewsID Desc,OrderRows Asc
4.CurrentPage :当前页码
5.PageSize :分页尺寸
6.Fields :字段
7.Filter :过滤语句，不带Where
8.Group :Group语句,不带Group By
9.GetCount :返回记录总数, 非 0 值则返回

然后再程序里调用存储过程
