  is
  begin
  insert into email_info(fullname,email_address) values (namee,address);
  end;
  //调用过程
  call add_emailinfo('cherry','asdfsdf');
  /////////////////////////////////////////////////////////////////////////////////////
  //创建函数
  create or replace function sel_emailinfo(namee email_info.fullname%type )
  return varchar2 is
  address varchar2(30);
  begin

  return address;
