Mysql ANY NOT EQUAL TO 子查询不工作

Question

我在使用 ANY 进行查询时遇到了一个小问题。

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;

查询运行但不排除在子查询中找到的项目。

当 子查询 中只有 1 行时，原始查询有效。一旦我添加更多，我就会收到关于超过 1 行的错误。

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;

从那里我添加了 ANY 并且查询运行但似乎忽略了 !=。我猜我在这里遗漏了一些东西。

谢谢

你为什么不使用 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;
