在SQL Select上，如果我想在另一个表中查询可选数据，如何避免得到0结果？

| OrderID | CustomerID | OrderDate |
|---------|------------|-----------|
| 1       | 1          | 2023-01-01|
| 2       | 2          | 2023-01-02|
| 3       | 3          | 2023-01-03|

| CustomerID | CustomerName |
|------------|--------------|
| 1          | John         |
| 2          | Jane         |

SELECT Orders.OrderID, Orders.OrderDate, Customers.CustomerName
FROM Orders
LEFT JOIN Customers ON Orders.CustomerID = Customers.CustomerID;

| OrderID | OrderDate   | CustomerName |
|---------|-------------|--------------|
| 1       | 2023-01-01  | John         |
| 2       | 2023-01-02  | Jane         |
| 3       | 2023-01-03  | NULL         |
