A friend gave me that hint with the DATE_FORMAT function in MySQL to get all post within a month; real handy:
SELECT * FROM posts WHERE DATE_FORMAT( postdate, \’%Y-%m\’ ) = \’2003-07\’;
Yet another query helps to get the posts per month based on a different solution (not using the date formatting):
SELECT substring( postdate, 1, 7 ) AS months, COUNT( ID ) FROM posts GROUP BY months
