Question

i have a pictures table : pictures(articleid,pictureurl)

And an articles table : articles(id,title,category)

So, briefly, every article has a picture, and i link pictures with article using articleid column. now i want to select 5 pictures of articles in politic category.

i think that can be done using IN but i can’t figure out how to do it.

Note: Please only one query, because i can do it by selecting articles firstly then getting the pictures.

Thanks

If you are looking for an IN query instead of a JOIN this is an alternative to Alex’s query:

SELECT pictureurl 
  FROM pictures 
  WHERE arcticleid IN (SELECT id FROM articles WHERE category='politic') 
  LIMIT 5
