How to Group Data Month when Using Datetime Column MySQL >

Try this:

GROUP BY date(ActionTime) or:

Assuming you store the date and time under the datetime column, to query it you want to count the results according to group by date, below is the format:

SELECT DATE_FORMAT(postdate, '%Y-%m-%d') AS dd, COUNT(id) FROM MyTable GROUP BY dd;

Or you can also try the upgraded query and use the string below:

SELECT substring(postrdate, 1,10) AS dd, COUNT(id) FROM MyTable GROUP BY dd;

This works faster than the first, but whichever works for you, will do.
