In this short article we would like to show how in MySql group rows by days.

Sql example:

SELECT 
	COUNT(`creation_time`) AS `count`, 
	DATE_FORMAT(`creation_time`, '%Y-%m-%d') AS `day`
FROM clients
GROUP BY YEAR(`creation_time`), MONTH(`creation_time`), DAY(`creation_time`)

Note: YEAR(`creation_time`) and MONTH(`creation_time`) prevents rows mixing when months come from different years.
