Question

i have a sql statement:

SELECT user.id, user.nickname 
FROM friends 
LEFT JOIN user ON user.id=friends.desuser where friends.orguser = '".$sessionid."' 

it works fine and results are like

12  user1
33  user3
etc

but when in my user DB lets say user1 is deleted, but still there is a record in friends.desuser, I get as result NULL NULL .

What can i do that I minimum would get the UserID like

12  NULL
33  user3

thank you

Answer 1

If you really want to return user IDs like that from friends that have been orphaned,

SELECT friends.desuser, user.nickname

instead of

SELECT user.id, user.nickname

since the id will not exist in user (since there’s no matching record in user)
