SELECT id HAVING maximum count of id

Question

Have a products table with item_id and color_id. I\'m trying to get the color_id with the most non-null instances.

This fails:

SELECT color_id 
           


        

Answer 1

SELECT color_id AS id, COUNT(color_id) AS count 
FROM products 
WHERE item_id = 1234 AND color_id IS NOT NULL 
GROUP BY color_id 
ORDER BY count DESC
LIMIT 1;

This will give you the color_id and the count on that color_id ordered by the count from greatest to least. I think this is what you want.

for your edit...

SELECT color_id, COUNT(*) FROM products WHERE color_id = 3;
