PL/SQL...Unsure how to loop thru multiple questions and display output?

Question

This is my first pl/sql program, I've written psudocode on paper, but not sure what to do for two parts.
What I'm trying to do is write pl/sql that will check a row based on an employee id #.
declare
cursor cur is
select *
from employee
where employee_id = foo;What we are checking are the results the employee answered. They have answered 180 questions and I want to find when the answer a 0, 7, and 9.
Basically the pl/sql has to loop thru the 180 questions
loop
v_count := vcount + 1
select *
from employee
where q1 thru q180 in (0, 7, 9);
end loop;
dbms_output.put_line ('Employee ID' || employee_id);
dbms_output.put_line ('Q1 - Q180' || q1 - q180); I'm not sure how to write the pl/sql to loop thur all 180 questions.
I'm not sure how to display the output to show what question they scored a 0, 7, and/or a 9 on.
thanks

536 columns in one table? Yowsa. Without a normalized table, you are going to need dynamic pl/sql and a messy solution.
I would rethink your design, and come up with something more like so:
employee
questions
employee_responses
So that would you could easily do something like this:
declare
  cursor c1 is
    select ers.question_id,
           que.question_name,
           ers.rating
      from employee emp,
           questions que,
           employee_responses ers
     where emp.employee_id = ers.employee_id and
           que.question_id = ers.question_id and
           emp.employee_id = v_employee_id and
           ers.rating in (0, 7, 9) and
           que.enabled_flag = 'Y';
begin
  for r1 in c1 loop
    dbms_output.put_line('Question: '||r1.question_name);
    dbms_output.put_line('Employee Rated this: '||r1.rating);
  end loop;
end;Thats how I would do it - I think you are going down the wrong path. What happens if you need to create a new question or delete one? You constantly have to modify the table. Hope this helps
