這個嘛,原來LeetCode有題目分類欸!?!?!?!

https://leetcode.com/problems/combine-two-tables/

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.

就是合併兩個Table啦～

透過PersonID進行Left Join就好了

select 
    a.FirstName,a.LastName,b.City,b.State 
from 
    Person as a left join 
    Address as b on a.PersonID = b.PersonID

果然做做簡單題目比較不會受挫

單純筆記，皆為非正規作法，旁門左道，胡搞瞎搞。
