如何在执行以下查询到codeigniter

后的最后十天获取日期

public function get_data() {
        $this->db->select('*');`enter code here`
        $this->db->select_sum('total_sale');

 $this->db->where('store_date BETWEEN CURDATE() - INTERVAL 7 DAY AND CURDATE()');
        $query = $this->db->get('one_month_report');
        if ($query->num_rows() > 0) {
            return $query->result();
        } else {
            return FALSE;
        }
    }

Answer 1

如果您的数据库将这些值存储为DATETIME或TIMESTAMP，则应该可以正常工作。

$start_date = date("Y-m-d 00:00:00", strtotime("-1 week"));

$end_date = date("Y-m-d 59:59:59");

$this->db->where("store_date >= '" . $start_date . "' AND store_date <= '" . $end_date . "'");

Answer 2

试试这个

public function get_data() 
{
    $query = $this->db->query("SELECT *, SUM(cast(REPLACE(total_sale, ',', '') as decimal(8,2))) 
                               FROM one_month_report 
                               WHERE store_date BETWEEN CURDATE() AND DATE(NOW()) - INTERVAL 7 DAY");
    $result= $query->result_array();

    if (empty($result)) {
        echo "Empty result";
    } else {
        return $result;
    }
}

确保CURDATE()返回日期

Answer 3

请试试这个：

$this->db->select('*');
$this->db->select_sum('total_sale');
$this->db->where('store_date BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()');
$query = $this->db->get('one_month_report');

Answer 4

这对我有用..

    $this->db->from('backbonedb'); 
    $this->db->where('status', $status);
    $this->db->where('date <=', date('Y-m-d'));
    $this->db->where('date >=', date('Y-m-d', strtotime('-7 days')));

    $this->db->order_by("id", "DESC");
    $query = $this->db->get();
