PLS-00103:在检查绑定变量中的值时遇到符号"EXCEPTION"错误

Question

我收到了我执行的PL/SQL块的以下错误.

ORA-06550:第16行,第1列:PLS-00103:遇到以下某种情况时遇到符号"EXCEPTION":

我在下面的匿名程序工作正常,直到我包括user defined exception e_nonrented.哪个检查bindvariable :g_movie_id=2..If 的值是否是它抛出异常的情况......

以下是代码:

VARIABLE g_movie_id NUMBER EXEC :g_movie_id := 2
DECLARE v_count NUMBER;
v_movieid NUMBER;
v_title mm_movie.movie_title%TYPE;
e_nonrented

 EXCEPTION;
BEGIN
  SELECT m.movie_title,
    COUNT(r.rental_id),
    r.movie_id
  INTO v_title,
    v_count,
    v_movieid
  FROM mm_movie m,
    mm_rental r
  WHERE m.movie_id = r.movie_id
   AND m.movie_id = :g_movie_id
  GROUP BY m.movie_title,
    r.movie_id;
  DBMS_OUTPUT.PUT_LINE(v_title || ': ' || v_count);

  IF :g_movie_id = 2 THEN
    RAISE e_nonrented;

  EXCEPTION
  WHEN no_data_found THEN
    DBMS_OUTPUT.PUT_LINE('there is no movie id for: ' || :g_movie_id);
  WHEN e_nonrented THEN
    DBMS_OUTPUT.PUT_LINE(' Movie with Id ');
  END;

Answer 1

你只是错过了一个END IF;陈述.

  IF :g_movie_id = 2 THEN
    RAISE e_nonrented;
  END IF;

EXCEPTION
