loop
fetch ailec into metrik;
exit when ailec%NOTFOUND;
If ailec%FOUND then --if metric no found
open iomega;
loop
fetch iomega into subject;
exit when iomega%NOTFOUND;
if iomega%FOUND then --if course_code found
alert := show_alert('success');
luck := 0;
while luck < 1 loop
--if cursor same with :block_course.course_code
if (subject.course_code = :block_course.course_code) then
alert := show_alert('part1');
--if cursor not same with :block_course.course_code
elsif(subject.course_code !=:block_course.course_code)
then
alert := show_alert('part2');
commit;
end if;
