Find Case 1 and Case 2

Question

Hi,
An order will have both Case 1 and case 2 types.
Case 1 :One ordered_item_id has multiple package _id which we call Ship Alone
Case 2: One package_id has multiple ordered_item_id which we call Normal
Requirement: I will give packing_id or ordered_item_id and how do I find out whether that packing_id
will fall in Case 1 or Case 2.
Sample Data:  *Ship Alone*
              Ordered_item_id  Ord_quantity         Packing_Id           packing_quantity
                  5858                 3              102,103,104        1,1,1          
              *Normal*
              Packing_Id        packing_quantity       Ordered_item_id    Ord_quantity            
            110                    2                           5111                 2
           110                    3                            5112                3
           110                    1                            5113                1
           110                    1                             5114               1                    I have tried this code but it is not giving me expected result.
       CURSOR c_count     
  IS
       SELECT oi.ordered_item_id
                 ,oi.quantity_ordered
                  ,SUM(pd.quantity)
                  ,COUNT(packing_id)
                    FROM  ordered_items oi
          ,packing_details pd
       WHERE oi.ordered_item_id = pd.ordered_item_id
         AND   oi.ordered_item_id = v_ordered_item_id
               GROUP BY  oi.ordered_item_id
                              ,oi.quantity_ordered;     
     OPEN c_count;
        LOOP
        FETCH c_count
      INTO ord_itm_id
               ,order_qty
              ,package_qty
              ,count_pack_per_item ;
       EXIT WHEN c_count%NOTFOUND;
       IF count_pack_per_item =1 THEN
--ddooo something
SELECT  COUNT(*)
      INTO v_shipalone_count
FROM packing_details pd
           ,packing p
WHERE pd.ordered_item_id = ord_itm_id
    AND p.packing_id       = pd.packing_id
   AND p.status           = 'C';     
  If (count_pack_per_item > 1) AND (v_shipalone_count >= 1)  THEN            
--do somethingthis is not complete code but the part which i trying to get the result
Suupose I give packing_id 103 then it should say it will come in Case 1.
Thanks in advance.

Answer 1

Thanks as you said Select are woking perfectly fine and seleting cases proeprly but I have problem how to implemet
those selects in my code.. here is my code and at step 6 & 7 im finding out ship_alone or normal case.
Please help me to resolve it.
--Stpe 5  find out number of packages in given order
     SELECT count(*)
       INTO package_count
       FROM packing
      WHERE client         = v_client
         AND order_number = v_order_number
                     AND status IN ('A','C');
--Step 5a. If only one package for a given Order UPDATE Order status = 'B' else Order status will remain 'S'--
     IF package_count = 1 THEN
       UPDATE orders
            SET status = 'B'
        WHERE order_number = v_order_number
                       AND client       = v_client;
     END IF;
-- -Step 5b. for all Orders (single or multiple packages) UPDATE ordered_items SET status = 'B'---     
        UPDATE ordered_items
           SET status = 'B'
                 WHERE client  = v_client
                    AND ordered_item_id   = v_ordered_item_id;
     IF package_count > 1 THEN
--Step 6. Check ordered_item_id count and packing_id count in given order_number
   OPEN c_count;
      LOOP
       FETCH c_count
      INTO ord_itm_id
           ,order_qty
           ,package_qty
           ,count_pack_per_item ;
       EXIT WHEN c_count%NOTFOUND;
--Step 6a. package has one/multiple order items       
       IF count_pack_per_item =1 THEN
           cmn_backorder_pkg.create_new_backorder (ordrec);  -- Create backorder from backordered items for ordrec.order_number.
     END IF;
---Step 6b. Ship-alone means order item has multiple pacakges
     SELECT COUNT(*)
                   INTO v_shipalone_count
       FROM packing_details pd
                          ,packing p
                WHERE pd.ordered_item_id = ord_itm_id
         AND p.packing_id          = pd.packing_id
         AND p.status                = 'C';     
---Step 7a Ship alone Order items has already one/more package cancelled
  If (count_pack_per_item > 1) AND (v_shipalone_count >= 1)  THEN
        UPDATE ordered_items oi
              SET oi.quantity_ordered = order_qty+package_qty
         WHERE ordered_item_id     = ord_itm_id ;
------step 7b Canceling Ship Alone package for first time      
   ELSE
       OPEN c_back_order;
       LOOP
          FETCH c_back_order
          INTO ordrec;
          EXIT WHEN c_back_order%NOTFOUND;
--Step 8a: Adjust original order items quantity --
      p_new_qty :=  (order_qty - package_qty);
          UPDATE ordered_items oi
                SET oi.QUANTITY_ORDERED = p_new_qty
           WHERE ordered_item_id = ord_itm_id;
    ---Step 8b: adjust packing detail quantity
            v_tran        := 'U';
            v_line_status := 'S';
            v_new_qty     := p_new_qty;
            OPEN c_adj_item (v_order_number, v_client);
            LOOP
              FETCH c_adj_item INTO itemrec;
              EXIT WHEN c_adj_item%NOTFOUND;
                .l              
         END LOOP;
         CLOSE c_back_order;  --c_back_order
       Thanks
