Question

The problem is that I’m using a table that has more than one reference to another table; basically I’m storing three different values for the original artist of a song, if it is featuring another artist, and if it is a remix or not. Each of these link to the artist table and what I want is to be able to return the artist name (no other data) for each of these columns. I have this so far:

SELECT `songName`, `songTrackNumber`, `artist`.`artistName`,
songFeaturingArtist, songRemixByArtist
FROM `song`
LEFT JOIN artist ON songArtist = artistID

I’m not entirely sure how to convert the other two fields from their numeric ID to the name of the artist. Any pointers would be greatly appreciated.

Answer 1

Join table Artist on table song three times to get the artistName for all the other columns on table song.

SELECT  a.songName, 
        a.songTrackNumber, 
        b.artistName AS ArtistName,
        c.artistName AS FeaturingArtist,
        d.artistName AS RemixByArtist
FROM    song a
        LEFT JOIN artist b ON a.songArtist = b.artistID
        LEFT JOIN artist c ON a.songFeaturingArtist = c.artistID
        LEFT JOIN artist d ON a.songRemixByArtist = d.artistID
