VC中如何调用返回记录集的存储过程，请高人指点迷津！

呵呵，上面说的很详细了

[llm06]

m_pConnection.CreateInstance("ADODB.Connection");
/******************连接数据库********************/
try
{
m_pConnection->ConnectionTimeout = 8;
//连接SQL SERVER
//m_pConnection->Open("Driver=SQL Server;Database=test;Server=127.0.0.1;UID=sa;PWD=;","","",adModeUnknown);
//连接ACCESS2000
//m_pConnection->Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=userinfo.mdb","","",adModeUnknown);
//连接到oracleMSDAORA oraoledb.oracle
m_pConnection->Open("Provider=oraoledb.oracle;Data Source=ep;User ID=zongdui;Password=zongdui;PLSQLRSet=1","","",adModeUnknown);

}
catch(_com_error e)///捕捉异常
{
AfxMessageBox("数据库连接失败!");
return FALSE;
}
/**********************************************/

上面是连接数据库，PLSQLRSet=1这个一定要有。

m_bNewUser = FALSE;
m_pRecordset.CreateInstance("ADODB.Recordset");
try
{
//m_pRecordset->Open("SELECT name as username,old,photo as photo1 FROM test",_variant_t((IDispatch *)theApp.m_pConnection,true),adOpenStatic,adLockPessimistic,adCmdText);
_CommandPtr pCmdChange = NULL;
// _ParameterPtr pprmByRoyalty = NULL;

pCmdChange.CreateInstance(__uuidof(Command));
pCmdChange->CommandType = adCmdStoredProc;
pCmdChange->CommandText = "pkg_test.get";


//Define Integer/variant.
// pprmByRoyalty.CreateInstance(__uuidof(Parameter));
// VARIANT vtRoyalty;
// vtRoyalty.vt = VT_I2;
// vtRoyalty.iVal = 20;
// pprmByRoyalty = pCmdChange->CreateParameter("param1",adInteger,adParamInput,sizeof(int),vtRoyalty);
// pCmdChange->Parameters->Append(pprmByRoyalty);

// pprmByRoyalty->Value = vtRoyalty;

//Create Recordset by executing the command
pCmdChange->ActiveConnection = theApp.m_pConnection;

//Create Recordset by executing the command
m_pRecordset->CursorType=adOpenStatic;
m_pRecordset->LockType=adLockPessimistic;
m_pRecordset = pCmdChange->Execute(NULL,NULL,adCmdStoredProc);
//m_pRecordset->Open("{CALL (?{20})}",_variant_t((IDispatch *)theApp.m_pConnection,true),adOpenStatic,adLockPessimistic,adCmdStoredProc);
/**/
}
catch (_com_error e)
{
AfxMessageBox(e.Description());
return FALSE;
}

这样就可以得到pkgtest.get返回的记录集
