Question

Lets say I have 2 tables in my db

user:
id, username

userpost:
userid, post

I have defined a Relation to connect userpost.userid to user.id in side the db (mysql).

Is there a query (as simple as possible) to pull the whole row (including user’s row)
WITHOUT knowing the relationship at the programmer side? meaning, relaing on the relationship defined in the db itself

something like "SELECT * from userpost include foreign key"

Answer 1

SELECT user.*, userpost.* 
  FROM user, userpost 
 WHERE user.id=userpost.userid

Possible problem would be the 1:many relationship between user and userpost: You would get each user-record multiple times (once for each userpost record)
