How can i get last week, current week and last month record from mysql

问题

i am storing date in strtotime format in codeigniter. and week start from sunday.

$this->db->where($this->weight . '.create_date <=', 'curdate() - INTERVAL DAYOFWEEK(curdate())+6 DAY');
$this->db->where($this->weight . '.create_date >', 'curdate() - INTERVAL DAYOFWEEK(curdate())-1 DAY');

回答1:

For taking last week:

WHERE date BETWEEN date_sub(now(),INTERVAL 1 WEEK) and now();

For taking current week:

WHERE  YEARWEEK(`date`, 1) = YEARWEEK(CURDATE(), 1)

For taking last month:

year(date(FROM_UNIXTIME(u.create))) = year(CURDATE() - INTERVAL 1 MONTH)
and month(date(FROM_UNIXTIME(u.create))) = month(CURDATE() - INTERVAL 1 MONTH)
