Sir,

I want to connect C++ with Oracle . So that I can take data from menu made in c++ and Store data in Oracle tables .

ad

TESTHR(pConn.CreateInstance(__uuidof(Connection)));
TESTHR(pRS.CreateInstance(__uuidof(Recordset)));

try
{
pConn->Open("Provider=sqloledb;Data Source=Sydney;"
"Initial Catalog=radio;User Id=sa;Password=f1ng3rs;","","",adConnectUnspecified);
pRS->PutRefActiveConnection(pConn);
pRS->Open("SELECT artistname, albumname, songname, fileLocationASF, fileLocationRA, songID FROM song WHERE uploadedToISP=0 ORDER BY songID DESC;",
vtMissing, adOpenForwardOnly, adLockReadOnly, adCmdText);


while (!pRS->adoEOF)
{
vtArtist = pRS->Fields->GetItem((long)0)->GetValue();
vtAlbum = pRS->Fields->GetItem((long)1)->GetValue();
vtSong = pRS->Fields->GetItem((long)2)->GetValue();
vtFileLocationASF = pRS->Fields->GetItem((long)3)->GetValue();
vtFileLocationRA = pRS->Fields->GetItem((long)4)->GetValue();
vtSongID = pRS->Fields->GetItem((long)5)->GetValue();

strBuff.Format("%s - %s - %s", (char*)((_bstr_t)vtArtist), (char*)((_bstr_t)vtAlbum), (char*)((_bstr_t)vtSong));
BSTR bstrFilename = strBuff.AllocSysString();
if (ftpUploadFile(bstrFilename, m_strFTPServername, (char*)((_bstr_t)vtFileLocationASF), (char*)((_bstr_t)vtFileLocationRA), m_strFTPASFRoot, m_strFTPRARoot))
{
strBuff.Format("radioUpdateUploadedToISP %li", vtSongID.lVal);
//AfxMessageBox(strSQL);
BSTR bstrSQL = strBuff.AllocSysString();
pConn->Execute(bstrSQL, NULL, adExecuteNoRecords);
SysFreeString(bstrSQL);
pRS->MoveNext();
}
SysFreeString(bstrFilename);
}
pRS->Close();
pConn->Close();
}
catch (_com_error)
{

}

I have little experience with C++ and Oracle, but maybe you should take a look at this:

Hi,

You can use the standard ODBC API, provided by Microsoft.
It is a set of functions to access and use any database. The
detailed help on these functions and their usage is available in
MSDN.

You will also need any ODBC driver for the Oracle RDBMS. Common
ones are those from Oracle and Microsoft.

The Oracle ODBC driver for Oracle RDBMS (SQORA32.DLL) gets
installed when you install Oracle client on your machine.

The Microsoft ODBC driver for Oracle RDBMS (MSORCL32.DLL)
comes bundled with Win2K.

Hope this helps.

With best regards,
Sayan

I have done little bit work on it and make a small frame work which fullfill my requirment by directly calling Oracle Native API i.e. OCI (Oracle Call Interface).
