Question

declare
  course_id char(10);
  course_idA char(10);

cursor task3 
  is
      select c_id from certificationrequirement
      where pcp_id = 101;

cursor task3A
  is 
      select o.c_id from courseoffering o
      join co_enrolment ce
      on o.co_id = ce.co_id
      where ce.s_regno = 401 and ce.coe_completionstatus = 'P';

Begin
  open task3;

    DBMS_OUTPUT.PUT_LINE ( 'List of Course to take ');
    loop

      FETCH task3 into course_id;
      exit when task3%NOTFOUND;

      DBMS_OUTPUT.PUT_LINE ( course_id);

    end loop;
  close task3;

  open task3A;

    DBMS_OUTPUT.PUT_LINE ( 'List of Courses student has passed ');

    loop

      FETCH task3A into course_idA;
      exit when task3A%NOTFOUND;

      DBMS_OUTPUT.PUT_LINE (course_idA);

    end loop;
  close task3A;

  if (cursor task3 = cursor task3A )
  Then
    DBMS_OUTPUT.PUT_LINE ( 'Student can attempt the Certification exam ');
  Else
    DBMS_OUTPUT.PUT_LINE ( 'Student cannot attempt the Certification exam ');
  END if;

我正在使用一个光标列出学生需要学习的特定学位课程。第二个光标列出了他正在学习的学位课程。如果光标中的两个值都相等，他将有资格参加退出考试，否则他将无法参加。我已经写下了比较代码，但我认为上面不是正确的方法。

Answer 1

if (task3%rowcount = task3A%rowcount  )
              Then
              DBMS_OUTPUT.PUT_LINE ( 'Student can attempt the Certification exam ');
              Else
              DBMS_OUTPUT.PUT_LINE ( 'Student cannot attempt the Certification exam ');
              END if;
