oracle - 游标plsql使用select

我想从table1（etudiant）中获得一个值，以便使用slect在table2（employee）中使用该值，我使用cursor，但是我没有得到结果；你能帮我谢谢吗

    declare
           cle employee.id%type;
           cursor cur_test is select id from etudiant where name ='Hichem';
           no_data_found exception;
    begin

      open cur_test;

      loop
           fetch cur_test into cle;
           exit when cur_test%notfound;
      end loop;

      --dbms_output.put_line('ID IS ' ||cle);
      select * from employee where id=cle;

      if cur_test%rowcount=0 then
        close cur_test;
        raise no_data_found;      
      end if;
      close cur_test;

exception 
      when no_data_found then
        dbms_output.put_line('no data found');

end;
