MySQL select highest rated

Question

I have 2 columns, one called rating_average and one called rating_count.

I need to select the 3 rows with the highest rating with the rating count factored into the equation as well.

Answer 1

SELECT * FROM table ORDER BY rating_average DESC LIMIT 3

That may work, but you should post the schema so we can see exactly what you want.

Answer 2

How do you want to factor in the rating count exactly? If you wanted to limit it to say items with at least 3 ratings, you could do this:

SELECT rating_average, rating_count
FROM mytable
WHERE rating_count > 3
ORDER BY rating_average DESC
LIMIT 3

Answer 3

SELECT *
FROM table
ORDER BY rating_average DESC,
         rating_count DESC
LIMIT 3

That gives the first 3 rows, sorted first by rating_average and then by rating_count.

Example:

=================================
| rating_average | rating_count |
=================================
|       9.1      |       5      |
|       8.9      |       9      |
|       8.9      |       3      |
=================================

Answer 4

You can do math in the order by clause, like:

select    *
from      YourTable
order by  rating_average * rating_count DESC
limit     3

In MySQL, you can add limit at the end of a query to restrict the rowset to the first N rows.

If you'd give an example, we could probably provide you with a more specific solution.
