Leetcode 175. Combine Two Tables数据库

SQL Schema

Table: Person

+-------------+---------+
| Column Name | Type    |
+-------------+---------+
| 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 |
| State       | 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

我学的是SQL标准语法，和MySQL语法其实不太一样

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

sql语句应该是这样的：

# Write your MySQL query statement below
SELECT FirstName, LastName,Address.City,Address.State 
from Person,Address 
where Person.PersonId = Address.PersonId;
