How to sort data in PL/SQL table and print them in Order?

Question

Hi Guys
I wan to create a csv file layout as below, maximum we got 12 weeks sales figure for each item. Week is week of the year, it will different every time based on sales_date.
Item Number     Description     Sales Week      27 26 25 24 23 22 21 20..
1234          Sample                10     6     2     8     10          
1230          Test                50     60     2      10          
I got item number, description, week_no and sales in a temp table which is populated by a procedure. Now I need to write these records from table to a file.
I not sure how to store multiple records for each item in PL/SQL table, sort them and print them in above format.
My select statement is as below
select item_number,
description,
week_no,
year,
opening_stock_qty,
production_qty,
sales_qty,
creation_date,
(production_qty - sales_qty) net_qty
from xxsu_planning_report
order by item_number,year,week_no;
Any help will be much appreciated.
Thanks and regards

Above error occured because you are trying to concatenate dbms output with some other string, which is not allowed.
Declare
TYPE plan_type IS TABLE OF xxsu_planning_report%ROWTYPE
INDEX BY BINARY_INTEGER;
plan_table plan_type;
BEGIN
plan_table(1).week_no := 24;
plan_table(1).description := 'This is week 24';
plan_table(2).week_no := 21;
plan_table(2).description := 'This is week 21';
for i IN 1..2 loop
dbms_output.put_line(plan_table(i).week_no) || ' ' || plan_table(i).description);
end loop;
END;From your code, I didnt understood what you want to do. Using Associative Array would be wrong approach in this case.
As per your scenario, you have to store max 12 records for each item number.
create or replace type dailySales as object(Description varchar2(100), Sales number,  Week number);
create or replace type saletab as table of dailySales;
create table t_sales (p_item number, p_sales saletab);
insert into t_sales values
(p_item, ---------enter value for item number 1
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 1
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 2
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 3
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 4
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 5
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 6
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 7
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 8
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 9
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 10
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 11
saletab(dailySales($n1,$n2,$n3)) ---------enter value for sales record for week 12
Enter 0 if no sales exist for any week. Because NULL would throw an exception.
Execute the SQL query to check the output.Try this and let me know if any fyrther issues.
