vc odbc 利用delete删除记录时出现异常提示

   

if((!m_pMySet->IsBOF()))
   
            m_pMySet->MoveFirst();
            while(!(m_pMySet->IsEOF()))
            {
                m_pMySet->Delete();
                if(!m_pMySet->IsBOF())
                    m_pMySet->MoveFirst();
                m_pMySet->Requery();
                if(m_pMySet->IsEOF())
                    break;
            }
代码运行到循环delete处时出现异常！！
 CATCH_ALL(e)
    {
        lResult = AfxGetThread()->ProcessWndProcException(e, &pThreadState->m_lastSentMsg);
        TRACE1("Warning: Uncaught exception in WindowProc (returning %ld).\n",
            lResult);
        DELETE_EXCEPTION(e);
    }
麻烦各位大侠有时间看下啊！1急用！！或有什么代替代码没？？
