新建数据库MyTest,建表t_Test,

SQL 安全性给角色分数据库权限,然后运行下列代码,数据库连接就如此的简单

#import "c:/Program Files/Common Files/System/ADO/msado15.dll" /
no_namespace rename("EOF", "EndOfFile")

#include <iostream>
#include <iomanip>
#include <stdlib.h>
#include <string>
using namespace std;

void main()
{
CoInitialize(NULL);

try
{
  _ConnectionPtr pConn("ADODB.Connection");
   _bstr_t strConnect= "Provider=SQLOLEDB.1;Persist Security Info=True;User ID=sa;Password=sa;Initial Catalog=MyTest;Data Source=127.0.0.1";
  pConn->Open(strConnect,"","",adModeUnknown);
  _RecordsetPtr pRs("ADODB.Recordset");
  pRs->Open("select * from t_Test", _variant_t(pConn,true), adOpenStatic, adLockOptimistic, adCmdText);

  while( !pRs->EndOfFile )
  {
   cout<<"name= "<<_bstr_t(pRs->GetCollect("Name"))<<"/t";
   cout<<"ID= "<<_bstr_t(pRs->GetCollect("ID"))<<"/t";
   cout<<"Value= "<<_bstr_t(pRs->GetCollect("Value"))<<"/n";
   pRs->MoveNext();

  }
  pRs->Close();
  pConn->Close();
}

catch(_com_error &e)
{
cout<<e.Error ()<<endl;

}
int a;
scanf("sssssssssssss",&a);

}
