表1: Person

+-------------+---------+
| 列名         | 類型     |
+-------------+---------+
| PersonId    | int     |
| FirstName   | varchar |
| LastName    | varchar |
+-------------+---------+
PersonId 是上表主鍵

表2: Address

+-------------+---------+
| 列名         | 類型    |
+-------------+---------+
| AddressId   | int     |
| PersonId    | int     |
| City        | varchar |
| State       | varchar |
+-------------+---------+
AddressId 是上表主鍵

編寫一個 SQL 查詢，滿足條件：無論 person 是否有地址信息，都需要基於上述兩表提供 person 的以下信息：

FirstName, LastName, City, State

Solution Code

# Write your MySQL query statement below
select Person.FirstName, Person.LastName, Address.City, Address.State
from Person
left outer join Address
on Person.PersonId = Address.PersonId;
 

SQL 組合兩個表
