The parent id links back to the main table. I'm sorry, I didn't
eleborate enough. There is one more table to note, the downloads
table. This table just matches member id's to song id's to see whos
bought what.
downloads
--------------------
member_ID (from user table, unimportant)
song_ID (links to both the main table and songs table)
so if my data looked like:
member_ID | song_ID
1 | 1
1 | 2
1 | 5
2 | 1
3 | 5
3 | 4
3 | 1
I'd want to query something like:
SELECT song_ID,songs.*,main.* from downloads,songs,main WHERE
downloads.member_ID = X <X being an int> AND songs.main_ID = main.ID
and songs.artist_ID = main.ID (obvious problem here)
The issue is that I need to get the name field and others from the
main table for each song and simultaneously get those same fields from
that same table from the artist_ID field in the same recordset, get
it? I'm thinking that there is no way to do this with sub-selects, is
it possible to do with PHP someway?
thanx,
J
