This bit of code should populate the playlist with five songs that appear in a playlist that has been saved to the RadioDJ database, randomly, and obey the settings for the track/artist repeat rules:

SELECT `songs`.`ID`, `songs`.`artist`, `songs`.`title` FROM `songs`
LEFT JOIN `queuelist` ON (`songs`.`ID` = `queuelist`.`songID` OR `songs`.`artist` = `queuelist`.`artist`)
LEFT JOIN `playlists_list` ON (`songs`.`ID` = `playlists_list`.`sID`)
WHERE `songs`.`enabled`=1
AND ((`start_date` = NOW() OR `end_date` = '2002-01-01 00:00:01'))
AND (TIMESTAMPDIFF(MINUTE, `date_played`, NOW())>$TrackRepeatInterval$ AND TIMESTAMPDIFF(MINUTE, `artist_played`, NOW())>$ArtistRepeatInterval$)
AND (`queuelist`.`songID` IS NULL OR `queuelist`.`artist` IS NULL)
AND (`playlists_list`.`pID` = '3')
ORDER BY RAND() LIMIT 5;

Note: The number value for the playlist ID in line AND (`playlists_list`.`pID` = '3') can be found in the playlists table…

Explanation of why one would wanna do this: Say I wanna have certain songs appear a little more often, and keep them in regular rotation… or, maybe I wanna create a special block/set of certain songs… Well, I go create a “playlist” using the playlist builder, save it, then add this code to the Tracks Rotation rules.

Other potential uses include using a playlist as a store for certain sets of commercials, etc., and having them loaded randomly or in order…

This bit of code should populate the playlist with five songs that have appeared in the requests table, randomly, and obey the settings for the track/artist repeat rules:

SELECT songs.ID, songs.artist, songs.title FROM songs
LEFT JOIN requests ON songs.ID= requests.songID
LEFT JOIN queuelist ON songs.ID = queuelist.songID OR songs.artist = queuelist.artist
WHERE songs.enabled=1
AND ((start_date <= Now()) AND (end_date >= NOW() OR `end_date` = '2002-01-01 00:00:01'))
AND (TIMESTAMPDIFF(MINUTE, date_played, NOW())>$TrackRepeatInterval$ AND TIMESTAMPDIFF(MINUTE, artist_played, NOW())>$ArtistRepeatInterval$)
AND (queuelist.songID IS NULL OR queuelist.artist IS NULL)
AND songs.ID= requests.songID
AND songs.song_type=0
ORDER BY RAND() DESC LIMIT 5;
