find_in_set AND find_in_set not working

Question

Trying to pull this query off, but it won't take ?

SELECT cute_news.title, cute_news.id, cute_news.keywords, cute_fields.post_id, cute_fields.alternate_url 
FROM cute_news, cute_fields 
WHERE cute_news.id = cute_fields.post_id AND 
FIND_IN_SET ('37',cute_news.category) AND 
FIND_IN_SET ('45',cute_news.keywords)

Not sure if I can't have two instances of FIND_IN_SET or what ?

Answer 1

Do both these queries return some common results?

Query 1

SELECT cute_news.title, cute_news.id, cute_news.keywords, cute_fields.post_id, cute_fields.alternate_url 
FROM cute_news, cute_fields 
WHERE cute_news.id = cute_fields.post_id AND 
FIND_IN_SET ('37',cute_news.category)

Query 2

SELECT cute_news.title, cute_news.id, cute_news.keywords, cute_fields.post_id, cute_fields.alternate_url 
FROM cute_news, cute_fields 
WHERE cute_news.id = cute_fields.post_id AND 
FIND_IN_SET ('45',cute_news.keywords)

Your query should return the intersection of Query 1 and Query 2. If either result set is empty, or if they have no results in common, then the final query will have no results.
