在SQL2005中如何用触器实现到客户端的通知？我写了一个存储过程，用Socket发信息，但提示权限错误。郁闷，
存储过程是这样的：
-------------------------------
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using System.Net;
using System.Net.Sockets;
using System.Text;

public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void SendMessage(string Msg)
{
// 在此处放置代码
TcpClient client = new TcpClient();
client.Connect(IPAddress.Parse( "221.7.229.*** "), 23456);
byte[] buffer = Encoding.ASCII.GetBytes(Msg);

client.GetStream().Write(buffer, 0, buffer.Length);

client.Close();
}
};

-------------------------------
错误提示是：
消息 6522，级别 16，状态 1，过程 SendMessage，第 0 行
在执行用户定义例程或聚合 'SendMessage ' 期间出现 .NET Framework 错误:
System.Security.SecurityException: Request for the permission of type 'System.Net.SocketPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 ' failed.
System.Security.SecurityException:

at System.Security.CodeAccessPermission.Demand()
at System.Net.Sockets.Socket.CheckCacheRemote(EndPoint& remoteEP, Boolean isOverwrite)
at System.Net.Sockets.Socket.Connect(EndPoint remoteEP)
at System.Net.Sockets.TcpClient.Connect(IPEndPoint remoteEP)
at System.Net.Sockets.TcpClient.Connect(IPAddress address, Int32 port)
at StoredProcedures.SendMessage(String Msg)
。


请高手帮忙呀，或都有什么更好的方法可用，谢告诉小弟，感激涕零。
