testingpoke1 - Tuesday, November 28, 2017 8:31 AMProcess: - When user buy item and check out then there's cart and cart items table to store the transaction.
- 1 cart_id have many item which stored in cart items table.
- After purchase succeed, then will generate a purchase order id and stored in purchase order table .
- In purchase order table, id_cart and status will be stored.From here, i am trying to calculate quantity based on id_product or id branch or etc from the purchase made.
There is receiving and ordered quantity field, which in some cases quantity received field might be null, so i will take ordered quantity value.
So why do you think id_product 3 should be in your results? You have no row in the purchase table for id_cart 2.
