Customers Who Never Order

Suppose that a website contains two tables, the Customers table and the Orders table. Write a SQL query to find all customers who never order anything.
Table: Customers.

+----+-------+
| Id | Name  |
+----+-------+
| 1  | Joe   |
| 2  | Henry |
| 3  | Sam   |
| 4  | Max   |
+----+-------+

Table: Orders.

+----+------------+
| Id | CustomerId |
+----+------------+
| 1  | 3          |
| 2  | 1          |
+----+------------+

Using the above tables as example, return the following:

+-----------+
| Customers |
+-----------+
| Henry     |
| Max       |
+-----------+ 

值得纪念的一次，第一次做出一道数据库的题，我没有任何数据库基础可言，全是自学youtube Standford 那个教程的（https://www.youtube.com/watch?v=D-k-h0GuFmE&list=PL6hGtHedy2Z4EkgY76QOcueU8lAC4o6c3），觉得这道题好简单啊。

 SELECT Name AS Customers  
 FROM Customers  
 WHERE Id NOT IN  
 (SELECT CustomerId AS Id FROM Orders);  

发图一张，特此纪念。
