数据访问？..一般的asp.net中是用存储过程来实现分页。然后定义一个管理分页的控件、或者类.来实现灵活的控件。

ALTER    PROCEDURE Data_PageView_SelectMax
@tblName     nvarchar(200),        ----要显示的表或多个表的连接
@fldName     nvarchar(500) = '*',    ----要显示的字段列表
@pageSize    int = 10,        ----每页显示的记录个数
@page        int = 1,        ----要显示那一页的记录
@fldSort    nvarchar(200) = null,    ----排序字段列表或条件
@Sort        bit = 0,        ----排序方法，0为升序，1为降序(如果是多字段排列Sort指代最后一个排序字段的排列顺序(最后一个排序字段不加排序标记)--程序传参如：' SortA Asc,SortB Desc,SortC ')
@strCondition    nvarchar(1000) = null,    ----查询条件,不需where
@ID        nvarchar(150),        ----主表的主键
@Dist                 bit = 0,           ----是否添加查询字段的 DISTINCT 默认0不添加/1添加
@pageCount    int = 1 output,            ----查询结果分页后的总页数
@Counts    int = 1                 ----查询到的记录数
AS
SET NOCOUNT ON
Declare @sqlTmp nvarchar(1000)        ----存放动态生成的SQL语句
Declare @strTmp nvarchar(1000)        ----存放取得查询结果总数的查询语句
Declare @strID     nvarchar(1000)        ----存放取得查询开头或结尾ID的查询语句

Declare @strSortType nvarchar(10)    ----数据排序规则A
Declare @strFSortType nvarchar(10)    ----数据排序规则B

Declare @SqlSelect nvarchar(50)         ----对含有DISTINCT的查询进行SQL构造
Declare @SqlCounts nvarchar(50)          ----对含有DISTINCT的总数查询进行SQL构造

以前找的一个..绝对可以用..因为正在用。哈哈

不好意思，借个地方问一下：上面这个分页过程效率怎么样呢？
