table MySQL db requête

Question

j'ai deux tables:

users{user_id, username, picture} 
likes{id, user_id, image_id} 

la requête im essayant de faire est:

select username, picture 
from user and from likes 
where user_id=user_id 
and image_id=4 

mais je dnt savoir comment les connecter, merci

Answer 1

La clé est d'utiliser un INNER JOIN entre les deux tables.

SELECT u.username, u.picture 
    FROM user u 
     INNER JOIN likes l 
      ON u.user_id = l.user_id 
    WHERE l.image_id = 4
