Using the getSales() function as a reference, create a function thatt will take one parameter (string code) which is a product code (or part thereof), and when the search button is pressed, all sales that include this product code (or part thereof) will be displayed in the jTable. The date boxes in the GUI will be replaced with a text box. The schema of the database where the queries are being used is also attached.

public List<Pos> getSales(String fromDate, String toDate){

List<Pos> salesList = new ArrayList<>();

try {

String query = "SELECT sales_date, sales_number, prod_code, prod_name, unit_cost, quantity, sales_total "

+ "FROM Sales, SalesDetails, Product "

+ "WHERE Sales.sales_number = SalesDetails.sales_number "

+ "AND SalesDetails.prod_code = Product.prod_id "

+ "AND sales_date BETWEEN ? AND ?";

PreparedStatement stmt = conn.prepareStatement(query);

stmt.setString(1, fromDate);

stmt.setString(2, toDate);

ResultSet rs = stmt.executeQuery();
