This is my table structure which i am using for the sql query:
SONGS MEDIA
id id
track song_id
artist source
added_on url
How can i insert a song (track,artist,added_on,source,url)? MEDIA.SONG_ID needs to be the correct SONGS.ID
MEDIA.ID and SONGS.ID
are both primary and auto increment.
Does anybody knows how to do this?
In standard SQL, you would use a transaction and the nextval
and currval
functions on the ID sequence:
BEGIN
INSERT INTO songs VALUES(nextval('songs_id_sequence'), ...);
INSERT INTO media VALUES(nextval('media_id_sequence'), currval('songs_id_sequence'), ...);
COMMIT
1) First option
you can insert into SONGS, getting song id and after it insert into MEDIA http://dev.mysql.com/doc/refman/5.0/en/getting-unique-id.html
2) Second option
Using updatable view (built on top of this two tables) http://dev.mysql.com/doc/refman/5.1/en/view-updatability.html
3) Third option
Using stored procedure with logic similar as first option
