I have a playlists table:

pid | name 

1   | playlist 1 
2   | playlist 2
3   | playlist 3

and a songs table:

sid | name 

1   | song 1 
2   | song 2
3   | song 3

they are connection with this junction table:

pid | sid 

1   | 1 
1   | 2
1   | 3
2   | 2 
3   | 1

I already managed to get the join to work

SELECT      playlists.pid, songs.*
FROM        playlists
INNER JOIN  playlist_contains_song
ON          playlists.pid = playlist_contains_song.pid
INNER JOIN  songs
ON          playlist_contains_song.sid = songs.sid;

which gave me this result:

pid | sid | name 

1   | 1   | song 1    
1   | 2   | song 2
1   | 3   | song 3    
2   | 2   | song 2    
3   | 1   | song 1

Now I wondered if there’s a way to get this data ‘horizontally’. The preferred output should look like this:

pid | 1 | 2 | 3

1   | 1 | 1 | 1
2   | 0 | 1 | 0
3   | 1 | 0 | 0

Where the columns are the sid’s and the values stand for true or false, whether the song is part of the playlist or not.

Thanks in advance!
