Table: Person

| PersonId    | int     |
| FirstName   | varchar |
| LastName    | varchar |
+-------------+---------+
PersonId is the primary key column for this table.

Table: Address

+-------------+---------+
| Column Name | Type    |
+-------------+---------+
| AddressId   | int     |
| PersonId    | int     |
| City        | varchar |

+-------------+---------+
AddressId is the primary key column for this table.

Write a SQL query for a report that provides the following information for each person in the Person table, regardless if there is an address for each of those people:

FirstName, LastName, City, State


# Write your MySQL query statement below
# select p.FirstName,p.LastName,a.City,a.State from Person p left join Address a using PersonId;
# SELECT p.FirstName, p.LastName, a.City, a.State FROM Person p LEFT JOIN Address a USING (PersonId);
SELECT p.FirstName, p.LastName, a.City, a.State FROM Person p LEFT JOIN Address a USING (PersonId);
时灵时不灵的，好奇怪。。。有时候平台会报 内部错误。。。
