oracle For loop，隐式游标

使用for in  loop，实质是隐式游标，对于依据检索结果集进行处理的情况非常方便

  For r_sys In (Select staff_name From  v_tr_member where team_sn=m_team_sn order by rowid) 
  Loop
    if pass_summary is null then
       pass_summary:=r_sys.staff_name;
    Else
      pass_summary:=pass_summary||'，'||r_sys.staff_name;
    End If;
  End Loop;
