*Get the list of valid IDs from the remote database using the raw SQL
command
something like:*

con = connectionForURI("firebird://yourUserName:yourPassword@serverAddress
:3050/pat/to/database/database.file")

validIDs= "SELECT ID FROM SONGS_TABLE where ......"

returnedIDs = con.queryAll(validIDs)

# you get the list of valid IDs, something like this: [(1,), (2,), (3,),
(4,), (5,), (6,), (7,), (8,), (9,), (11,)]

*than:*

import random
randomID = random.choice(returnedIDs)[0]
randomSong = SongsTable.get(randomID)

HTH
