I have a table which links the userID and the friendID (which is another user) to say they are friends. If User 1 adds User 24 as their friend, the first row in the below table will happen If User 10 adds User 1 as their friend, the second row in the below table will happen
From there, even if User 1 is on either side, they are friends with the adjacent ID.
FRIENDS TABLE:
userID | friendID
-----------------
1 | 24
10 | 1
What I need to do now is: If User 1 is logged in, I need to display the people they are friends with. This query I have wrote:
SELECT DISTINCT (Users.username), friends.userID, friends.friendID FROM Users, friends WHERE Users.userID IN(SELECT userID FROM friends WHERE Users.userID = friends.userID) OR Users.userID IN(SELECT DISTINCT(userID) FROM friends WHERE Users.userID = friends.friendID)
Will bring back:
username | userID | friendID
-----------------------------
name1 | 10 | 1
name1 | 1 | 24
name2 | 10 | 1
name2 | 1 | 24
name1 = ID 1 name2 = ID 10
Is there a way where I can retrieve the logged in Users'friends (e.g. if ID #1 is logged in) whether they appear in the userID or friendID columns. and then, in this case, retrieve ID 24 and 10 because they are linked with ID #1, and then when it comes to displaying, eliminate ID # 1 from the list because it will bring up that they are friends with themselves.
Hope this makes sense and thank you in advance!
