¿HOW CAN I SELECT DATA FROM DIFERENT TABLES? MYSQL : I have these tables:

ARTICLE, ARTICLE_has_tag, TAG, POST_ARTICLE and USER.

I would like to take all from ARTICLE, then the name of one tag (even that they have more than one), the number of comments and the user who made it. ¿Is it possible? ¿Should I do more than one query?
