ADO读写DateTime方式

// 读取日期 var = m_pResultSet->GetCollect(_variant_t( "Birth_Time" ));       DATE            dt      = var.date; COleDateTime    da      = COleDateTime(dt); CString         strData = da.Format(_T( "%Y-%m-%d" )); m_GridList.SetItemText(m_nRow, m_nColumn, strData);     // 写入日期 COleDateTime    oleDate = COleDateTime::GetCurrentTime(); CString         strDate = oleDate.Format(_T( "%Y-%m-%d %H:%M:%S" ));   m_pBorrowRS->Fields->GetItem(_variant_t( "Borrow_Date" ))->PutValue(_variant_t(strDate));    m_GridList.SetItemText(m_nRow, m_nColumn, strDate);   或： COleDateTime    oleDate = COleDateTime::GetCurrentTime();   _variant_t  vtDate; vtDate.vt   = VT_DATE; vtDate      = oleDate.Format(_T( "%Y-%m-%d %H:%M:%S" ));   m_pBorrowRS->Fields->GetItem(_variant_t( "Borrow_Date" ))->PutValue(vtDate); m_GridList.SetItemText(m_nRow, 3, ( LPCTSTR )_bstr_t(vtDate));
