when no_data_found异常出错?

[a_stupid_boy]

create or replace procedure exception_test
as
vid int;
vname varchar2(20);
cursor gettest is select * from test;


begin
open gettest;

loop
fetch gettest into vid,vname ;
--insert data
-- if vYTYW > 0 then

-- end if ;
exit when gettest %notfound ;
end loop ;

EXCEPTION WHEN NO_DATA_FOUND THEN

dbms_output.put_line("no data found") ;
end;

编译时说NO_DATA_FOUND没有定义，这是怎么回事啊

[jxc]

dbms_output.put_line("no data found") ;
用单引号

dbms_output.put_line('no data found') ;

哈，我看错了，一直还以为是上面的异常那句出了问题呢.thx!
