如何为我的查询使用 JOIN？

Question

I have two tables.

One contains:

id, album name, description, etc...

Another contains:

id, album id, photo

I want to get album details and its photos through album id ?

How can I achieve this?

Can I use left join?

Answer 1

Assuming your tables are called Albums and Photos :

SELECT Albums.*, Photos.Photo
FROM Albums
LEFT JOIN Photos
ON Albums.id=Photos.album_id
WHERE Albums.id=42

Answer 2

select a.id, a.album_name ..., b.photo 
from albums a 
left join OtherTable b on a.id = b.album_id

Answer 3

SELECT * 
FROM album a JOIN photo p
ON a.id=p.album_id 
WHERE a.id= 11
