GROUP BY and case sensitivity

[james438]

SELECT article.title, article.ID, COUNT(*) AS count 
FROM article, art_cat_relationships 
WHERE art_cat_relationships.art_ID=article.ID 
AND 
(art_cat_relationships.cat_ID=22 OR art_cat_relationships.cat_ID=30) 
GROUP BY article.title 
HAVING count = 2 
ORDER BY title

My question is not as complicated as the query looks. I was noticing when double checking some values that there was an unusual false positive. I am grouping by the article titles so that only the rows pulled 2 times are displayed. In this case "Attendance program" and "attendance program" were considered to be the same since the titles were considered the same, however the titles for these two articles are actually different because in the first article the first letter of the title is capitalized where as in the second title the first letter is not capitalized.

Any idea why these titles are considered the same and how to get the query to be case sensitive? I didn't see anything mentioned MySQL documentation about case sensitivity for this function.

Not that it's all that important, but this is for my new article tags page where results can be further narrowed by multiple tags.

It appears this has to do with how the table was collated. If it was collated as case insensitive then the query results will be treated as such.
