The attached SQL statement isn't working.  Would someone talk a look at my syntax?

$q2 = "UPDATE documents AS d INNER JOIN document_tracks AS dt USING (doc_id) SET d.listens = '$listen_total' WHERE dt.doc_id = '$arr1[1]'";

For MySQL that syntax looks correct.
UPDATE table1 t1 INNER JOIN table2 t2 USING(id)
SET t1.data = 'some value'
WHERE t2.somecolumn = 'some other value'

Now that the syntax is definitely correct, I moved on and found the problem in a different spot.  Thanks.
