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

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    开发者_Go百科        1   
6            1

But I want it to return:

film_id
  7
  6

How do I return only 1 colomn?

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

This isn't phrased as a CakePHP question,although it's tagged as such.

However, in CakePHP:

$this->FilmGenre->find('list',array('fields'=>array('film_id','film_id','anime_id')));

or make use of derived table

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