Mysql ANY NOT EQUAL TO subquery not working - mysql

Question

I'm having a small issue with a query using ANY.
Select *, count(*) as m
from mp_bigrams_raw
where date_parsed=051213
and art_source='f'
and bigram != ANY(select feed_source from mp_feed_sources)
group by bigram
order by m DESC
limit 50;
The query runs but it's not excluding the items found in the subquery.
The original query worked when there was only 1 row in the subquery. Once I added more I got an error about more than 1 row.
Select *, count(*) as m
from mp_bigrams_raw
where date_parsed=051213
and art_source='f'
and bigram != (select feed_source from mp_feed_sources)
group by bigram
order by m DESC
limit 50;
From there I added ANY and the query runs but seems to ignore the !=. I'm guessing I'm missing something here.
Thanks

Answer 1

Why don't you use NOT IN
Select *, count(*) as m
from mp_bigrams_raw
where date_parsed=051213
and art_source='f'
and bigram NOT IN(select feed_source from mp_feed_sources)
group by bigram
order by m DESC
limit 50;

Answer 2

Try using a left join with an is null:
Select r.*, count(*) as m
from mp_bigrams_raw r
left join mp_feed_sources f on f.feed_source = r.bigram
where r.date_parsed=051213
and r.art_source='f'
and f.feed_source is null
group by r.bigram
order by m DESC
limit 50;

Answer 3

The condition ANY returns true (as far as the doc says), whenever the condition is true for any of the entries of the subselect, so if one of those selected fields is != bigram the clause evaluates to true.
NOT IN is what you want, so bigram is not in the list of selected values.
