当运行下面的代码时,我得到一个ORA-01001:无效光标不知道发生了什么,我将它转换为一个过程并开始发生;Wierd PL SQL无效光标
CREATE OR REPLACE PROCEDURE p_student_from_class_list (p_stu_id IN NUMBER)
IS
--Declaring a variable --
v_date date;
--Creating a Cursor to find data from using the p_stu_id paramenter--
CURSOR enrollments_cursor IS
SELECT enrollment_date, stu_id, class_id, status
FROM enrollments
WHERE stu_id = p_stu_id;
BEGIN
/*Changing the date so the code looks for the classes for the student
which was entered in the bind variable above for the last 10 years*/
v_date := add_months(SYSDATE, -120);
FOR v_enrollment_record IN enrollments_cursor
LOOP
--Displays the student's enrollment date, class ID and Current Status for each class >they taken in last 10 years,from the value which was entered in the bind variable--
IF v_enrollment_record.enrollment_date
between v_date AND SYSDATE THEN
DBMS_OUTPUT.PUT_LINE('Enrollment Date: '
||v_enrollment_record.enrollment_date
||' Class ID: '||v_enrollment_record.class_id
||' Status: '||v_enrollment_record.status);
END IF;
END LOOP;
--Closing the cursor --
CLOSE enrollments_cursor;
--Application Express processes the statement--
COMMIT;
--Telling Application Express the procedure has finished--
END p_student_from_class_list;
--Anonymous Block to run the Procedure--
BEGIN
p_student_from_class_list(--Student ID--);
END;
正如我所说的代码,当它在一个过程,但由于某种原因,创建它作为一个过程,现在给出了这样的错误是得到了工作。我一直在试图解决这个问题。
哇完全没有看到!非常感谢你,你的救星= D – Phyore 2013-05-03 11:29:04
没问题。顺便提一句,您可以将'v_date'作为[光标参数](http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/static.htm#CIHFAHFE)并将其用于光标的' WHERE条款;那么你不需要循环内的IF。 – 2013-05-03 11:34:55
谢谢你的信息:)由于被要求输入他们的问题,这些问题被设置在问题中。不幸的是,日期并没有被告知输入〜 – Phyore 2013-05-03 15:15:31
