Question

I’m trying to get names of users from a voting table, I can’t quite figure out how to get both the voter’s name and the votee’s name.

Simplified Votes Table

ID   voteeID    voterID
1    1          2
2    1          3
3    1          4
4    2          1
5    2          3
6    2          4

Simplified User Info Table

ID   username
1    Bob
2    Sam
3    Ed
4    Mark

Where I’m at:

SELECT votes.voteeID, votes.voterID, userinfo.username
FROM votes
JOIN ???

I was playing around with the join, but I’m kind of stuck. If I join on the votee’s id to the userinfo id, how would I also get the voter’s name or vice versa?

Database: MySQL 5

Any help or even a hint would be wonderful, thanks in advance.

Answer 1

try this one,

SELECT  b.`username` as Votee_Name,
        c.`username` as Voter_Name
FROM    Votes a
            INNER JOIN UserInfo b
                ON a.voteeID = b.Id
            INNER JOIN UserInfo c
                on a.voterID = c.id
