Question

I have the following MySQL table named “proposals”:

• proposal_id
• proposal_user (int
• proposal_book (int)
• proposal_date (Y-m-d)

Users are going to propose books each month so there will be like 50-100 books per month. I would like to know if there’s a way of writing a query that can return the most proposed books for a given month.

Thanks in advance.

Answer 1

SELECT  proposal_book, COUNT(*) AS cnt
FROM    proposals
WHERE   proposal_date >= $first_day_of_month
        AND proposal_date < $first_day_of_month + INTERVAL 1 MONTH
GROUP BY
        proposal_book
ORDER BY
        cnt DESC
LIMIT 10
