Question

I have a mysql database with

• table ‘product’ containing columns ‘product_id’, ‘name’, ‘price’
• table ‘review’ containing columns ‘review_id’, ‘product_id’, ‘review_content’

I want to retrieve results for ‘product_id’ = 123, but sort if by number of reviews. I am able to find the number of reviews for a particular product using COUNT(‘review_id’), but how do I sort the results by number of reviews?

Answer 1

Since you’re presumably selecting COUNT('review_id') in your query, you can simply add ORDER BY COUNT('review_id') DESC at the end.
