MySQL: How to group data per hour and get the latest hour

Question

I\'m trying to do a query that fetches data per hour but instead of the normal group by hour I want to narrow it down and only get the latest hour

Answer 1

Do you mean one hour from NOW or latest full hour? If it's latest full hour something like this might work?

SELECT userid, username, date_created
FROM user_accounts 
WHERE HOUR(date_created) = (SELECT HOUR(date_created) FROM user_accounts ORDER BY date_created DESC LIMIT 1);

EDIT: Ahhh, now I think I get what you want... The last added entry on every given hour between your date range?

If so then Codler's query is what you want.
