需要说明的是：这个存储过程参数比较多，我再实际使用中又在外面单独写了一个类，页面调用直接调用封装的类，方法有很多，主要是思路，大家可以参考下。
代码修改集中在类似
复制代码 代码如下:
if @Sort=0
set @strTmp = @strTmp + ‘<(select min(‘
else
set @strTmp = @strTmp + ‘>(select max(‘
另外94行主要是配合我自己写的类，显示记录条数分页数等信息，如果不需要就去掉。
复制代码 代码如下:
1ALTER PROCEDURE [dbo].[proc_ListPage]
2(
3 @tblName nvarchar(200), —-要显示的表或多个表的连接
4 @fldName nvarchar(500) = ‘*’, —-要显示的字段列表
5 @pageSize int = 10, —-每页显示的记录个数
6 @page int = 1, —-要显示那一页的记录
7 @fldSort nvarchar(200) = null, —-排序字段列表或条件
8 @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 ‘)
9 @strCondition nvarchar(1000) = null, —-查询条件,不需where
10 @ID nvarchar(150), —-主表的主键
11 @Dist bit = 0, —-是否添加查询字段的 DISTINCT 默认0不添加/1添加
12 @pageCount int = 1 output, —-查询结果分页后的总页数
13 @Counts int = 1 output —-查询到的记录数
14 )
15 AS
16 SET NOCOUNT ON
17 Declare @sqlTmp nvarchar(1000) —-存放动态生成的SQL语句
18 Declare @strTmp nvarchar(1000) —-存放取得查询结果总数的查询语句
19 Declare @strID nvarchar(1000) —-存放取得查询开头或结尾ID的查询语句
20
21 Declare @strSortType nvarchar(10) —-数据排序规则A
22 Declare @strFSortType nvarchar(10) —-数据排序规则B
23
24 Declare @SqlSelect nvarchar(50) —-对含有DISTINCT的查询进行SQL构造
25 Declare @SqlCounts nvarchar(50) —-对含有DISTINCT的总数查询进行SQL构造
