The UpdateCustomer method

The UpdateCustomer method prepares the UPDATE statement by passing the CustomerName and SSN from the customer object; this is shown in the following code:

// Update Customer method with parameter customerfunc UpdateCustomer(customer Customer) {     var database *sql.DB     database= GetConnection()     var error error      var update *sql.Stmt      update,error = database.Prepare("UPDATE CUSTOMER SET CustomerName=?, SSN=? WHERE CustomerId=?")          if error != nil {              panic(error.Error())          }          update.Exec(customer.CustomerName,customer.SSN,customer.CustomerId)     defer database.Close()}
