I am having trouble using CDaoRecordset::AddNew.   Basically I am trying to scan a table for a name.  If that name is not there, I want to add it.  Here is my code:


strQuery.Format("select ArtistID from Artists where ArtistName = '%s'", pszArtistName);
                  
CDaoRecordset* pRS = new CDaoRecordset(m_pDB);
CString cs("");

try
{
      pRS->Open(dbOpenDynaset, strQuery);

      int iRecords = pRS->GetRecordCount();

      if (!iRecords)
      {
            pRS->AddNew();
            pRS->SetFieldValue(2, pszArtistName);
            pRS->Update();
        }
}
catch (CDaoException* e)
{
      AfxMessageBox(e->m_pErrorInfo->m_strDescription, MB_ICONEXCLAMATION);
}

----

The problem is that every time I try to call SetFieldValue I get an exception that says "Item not found in this collection".   The new row (blank however) is added to the table, I just can't set my data for that row.

How can I accomplish this?

The dynaset you created with your open statement only has one
column ( ArtistID), trying to update the second column therefor
gives the grief.

Try
strQuery.Format("select * from Artists where ArtistName = '%s'", pszArtistName);
