ASP.NET如何调用MySQL的存储过程

转：QQ：772755070

 

由于项目中需要在ASP.NET中如何调用MySQL的存储过程，
百度和Google后发现中文的网站讲解也不是很清楚。
没有办法，只有自己动手。折腾一下午终于搞定，所以拿出来分享!
调用的存储过程虽然简单,但是麻雀虽小,五脏俱全.呵呵；）

首先必须下载支持.NET的驱动,有两种策略: 使用ODBC或Connector/Net
至于这两种方法中那种快些,查看网上的文章说是使用ODBC联结用时24秒，Connector/Net联结用时17秒
本人并没有去求证，但使用Connector/Net是肯定要方便的，呵呵。

Mysql的connector/net5.0下载地址: 
http://dev.mysql.com/get/Downloads/Connector-Net/mysql-connector-net-5.0.6.zip/from/pick 

安装好以后, 

点属性,然后点查找目标,点向上一层目录,找到Binaries/.NET 2.0,然后将这个文件复制到你的工程目录下,一般这样的DLL文件会保存到bin目录下. 

aspx页面UI层次的显示等就不讲解了，看看所谓的业务逻辑层的连接吧。。。。

procedure.cs类文件中：

public void Delete_procedure()  //“删除”的存储过程{    string str_orgid = Client_Str;  //获得orgid    string myConn_str = WebConfigurationManager.ConnectionStrings["MySqlConnectionString"].ConnectionString;    MySqlConnection myConn = new MySqlConnection(myConn_str);    MySqlCommand myComm = new MySqlCommand("DELETEDB", myConn);//(Client_Str);    //myComm.Connection = myConn;    try    {        myComm.Connection.Open();        myComm.CommandType = CommandType.StoredProcedure;        MySqlParameter myParameter;        myParameter = new MySqlParameter("?m_orgid", MySqlDbType.String);        myParameter.Value = str_orgid;        myParameter.Direction = ParameterDirection.Input;        myComm.Parameters.Add(myParameter);        //myComm.CommandText = "DELETEDB"; //存储过程名        //myComm.Parameters.Add("m_orgid", str_orgid);        myComm.ExecuteNonQuery();    }    catch    {        myComm.Connection.Close();        myComm.Dispose();    }    finally    {        myComm.Connection.Close();        myComm.Dispose();    }}

数据库当然是要自己建立的，由于“删除”的这个存储过程比较简单，能让大家容易理解
这个存储过程就是实现统一删除每一个相关数据表中的一条记录，只用了传递ID这一个参数。

Mysql的简单存储过程：

CREATE PROCEDURE `DELETEDB`(IN m_orgid char(12))BEGIN        delete from hardwareinfo where orgid=m_orgid;        delete from addressinfo where orgid=m_orgid;        delete from netspeedinfo where orgid=m_orgid;        delete from memoryinfo where orgid=m_orgid;        delete from urlinfo where orgid=m_orgid;        delete from urluserinfo where orgid=m_orgid;        delete from orderinfo where orgid=m_orgid;        delete from softinfo where orgid=m_orgid;        delete from orginfo where orgid=m_orgid;        delete from harddiskinfo where orgid=m_orgid;        delete from hotfixinfo where orgid=m_orgid;        delete from userinfo where orgid=m_orgid;        delete from softuserinfo where orgid=m_orgid;        delete from systeminfo where orgid=m_orgid;END
