各位大侠帮忙看看下面oracle代码哪错了啊，总说带有编译错误

 create or replace procedure p
  is

  cursor c is 
  select * from emp2 for update;
  begin
  for v_emp in c loop
  if (v_emp.deptno = 10) then
  update emp2 set sal = sal + 10 where current of c;
  elsif (v_emp.deptno = 20) then
  update emp2 set sal = sal + 20 where current of c;
  else
  update emp2 set sal = sal + 50 where current of c;
  end if;
  end loop;
  commit;
  end;
 /

编译通过，我用的是Scott方案下的emp表，你可以改回你的emp2表.
SQL code

CREATE OR REPLACE PROCEDURE p
IS

    CURSOR c IS SELECT * FROM emp FOR UPDATE;
BEGIN
    FOR v_emp IN c 
    LOOP
        IF v_emp.deptno = 10 THEN
            UPDATE emp SET sal = sal + 10 WHERE CURRENT OF c;
        ELSIF (v_emp.deptno = 20) THEN
            UPDATE emp SET sal = sal + 20 WHERE CURRENT OF c;
        ELSE
            UPDATE emp SET sal = sal + 50 WHERE CURRENT OF c;
        END IF;
    END LOOP;
    COMMIT;
END;
