Php 从表中选择，其中子句为interval

在这方面：

    $this->db->select('count(o.id)');
    $this->db->from('orders o');           
            $this->db->join('order_status_history', 'o.id =  order_status_history.order_id');
            $this->db->where("(order_status_history.in_dts)::date ='" .$reportDay. "'");
            $this->db->where('order_status_history.new_status ' , 6);

我想要选择count（id）where order_status_history.new_status是一个间隔，例如（2），因为我记得您可以将where语句添加为字符串，就像在本机sql查询中一样。 请试试这个：

    $this->db->select('count(o.id)');
    $this->db->from('orders o');           
        $this->db->join('order_status_history', 'o.id =  order_status_history.order_id');
        $this->db->where("(order_status_history.in_dts)::date ='" .$reportDay. "'");
        $this->db->where('order_status_history.new_status BETWEEN 2 AND 6');

这是否有效？

我记得您可以将Where语句作为字符串添加，就像在本机sql查询中一样。 请试试这个：

    $this->db->select('count(o.id)');
    $this->db->from('orders o');           
        $this->db->join('order_status_history', 'o.id =  order_status_history.order_id');
        $this->db->where("(order_status_history.in_dts)::date ='" .$reportDay. "'");
        $this->db->where('order_status_history.new_status BETWEEN 2 AND 6');

这有效吗？

您对此有何看法：

$this->db->select('count(o.id)');
$this->db->from('orders as o');           
$this->db->join('order_status_history', 'o.id =  order_status_history.order_id');
$this->db->where("(order_status_history.in_dts)::date ='" .$reportDay. "'");
$this->db->where_between('order_status_history.new_status ',2 , 6);

使用where\u-between引入id间隔！使用where\u-between引入id间隔！
