Question

There is a table Post in my database which contains posts of different users. What I wanna do is to create an sql query that’ll return as per respective month the number of posts being made each day. Kindly let me know how can i do that generically in one query i can create multiple queries for all days but that is a worst case scenario. So I need expert’s solution to this.
Thanks

Expected output:
(Query counts the number of posts for all the days in a respective month)

Day   :   Number of posts

1       :        20

2       :        25

3       :        10

4       :        17

…………………….

30       :        6

Table Structure:
ID | postid | post | date

Answer 1

SELECT DAYOFMONTH(date), count(*) FROM Post
GROUP BY DAYOFMONTH(date)
ORDER BY DAYOFMONTH(date) ASC;

If you want to query for a specific month (say, February) then use this:

SELECT DAYOFMONTH(date), count(*) FROM Post
WHERE MONTH(date) = '2'
GROUP BY DAYOFMONTH(date)
ORDER BY DAYOFMONTH(date) ASC;

Note: Months are returned in number form where the MONTH() function is used.

EDIT: If you’re looking to return counts for EVERY day in a given month, then I’d push you here – a great accepted answer to a similar question: How to get values for every day in a month
