編寫的SQL語句與JOIN

Question

所以我有3個表

----------------------- 
|  1  | alpha | 
|  2  | beta | 
|  3  | gamma | 

表2：建築

| building_id | name  | 
--------------------------- 
| 1   | Baxter | 
| 2   | LexCorp | 

表3：團隊位置

| team_id | building_id | 
------------------------- 
| 1 |  1  | 
| 2 |  1  | 
| 3 |  2  | 

我現在需要的是一個sql查詢將列出位於巴克斯特大廈球隊的名字，我不能爲我的生活甚至認爲從哪裏開始就這一個，即時通訊相當新的SQL

Answer 1

試試這個

SELECT team.name FROM team_location 
INNER JOIN buildings ON buildings.building_id = team_location.building_id 
INNER JOIN team ON team.team_id = team_location.team_id 
WHERE buildings.name = 'Baxter' 

Answer 2

SELECT t.NAME 
FROM team as t 
INNER JOIN teamLocation AS tl ON t.team_id=tl.team_id 
INNER JOIN buildings As b ON tl.building_id=b.building_id 
WHERE b.name='Baxter'
