user



id   |  name

article



id   | title | descritption
1 | wx | xyz
2 | yz | abc


article_rating



article_id(article->id)  |  given_by(user->id)  |  given_rating
1 2 4
2 1 3


saved_article



article_id(article->id)  |  saved_by(user->id) 
1 2


I'm changing some buttons and icons depending on whether a user has rated/ saved an article or not. I'm using two select queries for that:



rated or not



SELECT given_rating as rating 
FROM article_rating
WHERE given_by=? AND article_id=?


saved or not



SELECT saved_by as saved 
FROM saved_article
WHERE saved_by=? AND article_id=?


So my question is how can i combine both into one mysql query efficiently??
