175.Combine Two Tables

难度:Easy

SQL架构

``` 表1: Person

+-------------+---------+ | 列名 | 类型 | +-------------+---------+ | PersonId | int | | FirstName | varchar | | LastName | varchar | +-------------+---------+ PersonId 是上表主键 表2: Address

+-------------+---------+ | 列名 | 类型 | +-------------+---------+ | AddressId | int | | PersonId | int | | City | varchar | | State | varchar | +-------------+---------+ AddressId 是上表主键

编写一个 SQL 查询,满足条件:无论 person 是否有地址信息,都需要基于上述两表提供 person 的以下信息:
FirstName, LastName, City, State
代码如下:

Write your MySQL query statement below

SELECT p.FirstName,p.LastName,a.City,a.State FROM Address a RIGHT JOIN Person p on p.PersonId=a.PersonId;
