Jay,
That looks a lot more professional - thanks.
Where can I get information on writing better SQL?

DELETE bm_KW FROM bm_KW
INNER JOIN (
SELECT kw2.KeywordID
FROM bmjn_KW kw1
INNER JOIN bmjn_KW kw2
ON kw1.KeywordID = kw2.KeywordID
AND kw2.ItemID != '1016'
WHERE kw1.ItemID = '1016'
) AS keywords
ON bm_KW.KeywordID = keywords.KeywordID;

This query works but is there any way of making it more elegant or
speeding it up?
DELETE from bm_KW USING bm_KW, bmjn_KW
WHERE
bm_KW.KeywordID IN
(SELECT bmjn_KW.KeywordID FROM bmjn_KW
WHERE bmjn_KW.ItemID = '1016' ) AND
bm_KW.KeywordID NOT IN
(SELECT bmjn_KW.KeywordID FROM bmjn_KW
WHERE bmjn_KW.ItemID != '1016');
