ADO Recordset 对象中的updateBatch函数的使用方法(转)

1.设置 pRecord->CursorLocation = adUseClient;

2.open方法中设置lockType 为adLockBatchOptimistic

_RecordsetPtr pRecord;
    pRecord.CreateInstance("ADODB.Recordset");  

    pRecord->CursorLocation = adUseClient;  

    CString strSQL  ;
    strSQL.Append("SELECT * fROM emp ");  

    try
    {
        pRecord->Open(_bstr_t(strSQL),pConnection.GetInterfacePtr(),adOpenStatic,adLockBatchOptimistic,adCmdText);  

        CString strValue;
        while(!pRecord->AdoEOF)
        {
            strValue.Format("Test_%d",pRecord->AbsolutePosition);
            pRecord->PutCollect("name",_variant_t(strValue));
            pRecord->MoveNext();
        }  

        pRecord->UpdateBatch(adAffectAll);
        pRecord->Close();
    }
    catch(_com_error &e)
    {
        OutputDebugString(e.Description());
    }
