完整的ASP.NET存储过程分页，排序，鼠标移至变色

首先建立一个存储过程如下（MySQL数据库）：
CREATE DEFINER=`root`@`localhost` PROCEDURE `pagination`(
in tbName varchar(100), /*表名*/
fldName varchar(100), /*排序关键字*/
pageSize int, /*每页显示行数*/
pageIndex int, /*当前显示第几页*/
orderType int, /*排序规则 0升序，1降序*/
strWhere varchar(2000),/*查询条件 例如where 1=1*/
out allPages int /*传出参数 返回总行数*/
)
begin

declare beginRow int;
declare sqlStr varchar(1000);
declare limitTemp varchar(1000);
declare orderTemp varchar(1000);
declare allPageNum int;

set allPageNum = 0;
set beginRow = (pageIndex-1)*pageSize;
set sqlStr = CONCAT('SELECT * from ',tbName);
set limitTemp = CONCAT(' limit ',beginRow,',',pageSize);
set orderTemp = CONCAT(' order by ',fldName);
if orderType = 0 then
set orderTemp = CONCAT(orderTemp,' ASC ');
else
set orderTemp = CONCAT(orderTemp,' DESC ');
end if;

set @sqlSelect = CONCAT(sqlStr,' ',strWhere,orderTemp,limitTemp);

set @sqlCountRow = CONCAT('select count(*) into @countRow from ',tbName);

prepare sqlstmt from @sqlSelect;
execute sqlstmt;
deallocate prepare sqlstmt;

prepare sqlstmt from @sqlCountRow;
EXECUTE sqlstmt;
set allPages = @countRow;
deallocate prepare sqlstmt;

end;

建立一个排序类
using System;
using System.Data;
using MySql.Data.MySqlClient;

namespace TestMySQL
{
public class Procedure
{
public Procedure()
{
}

/// <summary>
/// 根据条件查询,返回一页记录
/// </summary>
/// <param name="tbName">要查询的表名 多个表之间用","分隔</param>
/// <param name="fldName">排序关键字段</param>
/// <param name="pageSize">每页显示行数</param>
/// <param name="pageIndex">显示第几页</param>
/// <param name="orderType">排序规则 0为升序,1为降序</param>
/// <param name="strWhere">查询条件 例如"where 1=1'</param>
/// <param name="allNum">返回总行数</param>
/// <returns>一页的记录</returns>
public static DataTable Query(string tbName,string fldName,int pageSize,int pageIndex,int orderType,string strWhere,out int allNum)
{

// MySqlConnection con = DB.CreateCon();
MySqlConnection con = new MySqlConnection("server=localhost; database=testprocedure; user id=root; password=123456");
MySqlCommand mySqlCmd = new MySqlCommand();
mySqlCmd.Connection = con;
mySqlCmd.CommandText = "pagination";
mySqlCmd.CommandType = CommandType.StoredProcedure;

//添加参数列表
mySqlCmd.Parameters.Add(new MySqlParameter("tbName",MySql.Data.MySqlClient.MySqlDbType.VarChar));
mySqlCmd.Parameters["tbName"].Value = tbName;

mySqlCmd.Parameters.Add(new MySqlParameter("fldName",MySql.Data.MySqlClient.MySqlDbType.VarChar));
mySqlCmd.Parameters["fldName"].Value = fldName;

mySqlCmd.Parameters.Add(new MySqlParameter("pageSize",MySql.Data.MySqlClient.MySqlDbType.Int32));
mySqlCmd.Parameters["pageSize"].Value = pageSize;

mySqlCmd.Parameters.Add(new MySqlParameter("pageIndex",MySql.Data.MySqlClient.MySqlDbType.Int32));
mySqlCmd.Parameters["pageIndex"].Value = pageIndex;

mySqlCmd.Parameters.Add(new MySqlParameter("orderType",MySql.Data.MySqlClient.MySqlDbType.Int32));
mySqlCmd.Parameters["orderType"].Value = orderType;

mySqlCmd.Parameters.Add(new MySqlParameter("strWhere",MySql.Data.MySqlClient.MySqlDbType.VarChar));
mySqlCmd.Parameters["strWhere"].Value = strWhere;

mySqlCmd.Parameters.Add(new MySqlParameter("allPages",MySql.Data.MySqlClient.MySqlDbType.Int32));
// mySqlCmd.Parameters["@allNum"].Value = allNum;
mySqlCmd.Parameters["allPages"].Direction = ParameterDirection.Output;

MySqlDataAdapter msda = new MySqlDataAdapter(mySqlCmd);
DataSet ds = new DataSet();
msda.Fill(ds,"temp");

allNum = Convert.ToInt32(mySqlCmd.Parameters["allPages"].Value);

return ds.Tables["temp"];
}
}
}
