By using the 'addBatch' method we can collate each row of student data into a single SQL statement that can be used to connect to the database once and execute multiple times. In order to do this we use 'prepareStatement' to which we can then feed in our values
var stmt = db.prepareStatement("INSERT INTO students (StudentNo, FirstName, LastName, Shoesize) "
+ "VALUES (?, ?, ?, ?)");
