- Suppose a qüery sumServ sums the quantities in the CustomerBillitem table and a query sumWaste sums the quantities in the FoodWaste table. For the purpose of summing the quantities in sumServ and sumWaste, the following query design needs: sumserv sunWaste Storeio Storeib FoodiD Foodio Sumoruantity SumorQuantity sen wastew 1) No join from servWk to wasteWk 2) A left outer join on FoodiD 31 Left outer joins on StorelD and FoodID 4) All left outer joinsUsing the getFirst() function as a template for reference, code the saveProduct() function that will be called when the save button of the depicted screen is clicked. The text from the JTextFields will be used as parameters.The database schema for the SQL tables are also depicted. The number of the product is the primary key and is set to auto-increment. public Product getFirst() { if (openConnection()) { try{ Product temp = null; String query = "SELECT * FROM products order by number asc limit 1"; // our SQL SELECT query.

Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100
