left joins are your key
select * from a
left join b on id = tbl_id and b.tbl = a
where b.tbl_id is null
(not 100% sure on my syntax, but note the join, and the limitation on 'left' result
set is specified within the left join clause)

Nope.
Ex.: select ... from ... where ... in (select.)
If not, has some version that supports it?
Subselects will come in 4.1

Hi Bill,

If I understand your question, you just need to join with the languages
table twice, using aliases:
select LF.language, LT.language
from language_pairs P, languages LF, languages
SELECT f.language as From, t.language as To
FROM language f, language t, language_pairs lp
WHERE f.id = lp.from
AND t.id = lp.to;

you can rewrite this query to simple joins so you dont use sub selects.
select media.media_id , media.price, media.filename
from media,category_locks,categories
where media.media_id = category_locks.media_id
and category_locks.category_id = categories.category_id
and categories.dynamic_media =
