How can one column in the result of a MySQL query be removed?

Question

Example:

SELECT `film_id`,COUNT(film_id) AS COUNT FROM films_genres AS FilmsGenre   
WHERE genre_id In (4)  
GROUP BY film_id,COUNT 
HAVING COUNT = 1 

return:

film_id |  COUNT
7            1   
6            1

But I want it to return:

film_id
  7
  6

How do I return only 1 colomn?

Answer 1

To do it, just move your "COUNT(film_id)". Your HAVING clause will do the work for you.

SELECT `film_id` FROM films_genres AS FilmsGenre
WHERE genre_id In (4)
GROUP BY anime_id,film_id
HAVING COUNT(film_id) = 1
