在 WHERE 条件下使用 BETWEEN [英] using BETWEEN in WHERE condition

问题描述

我想要以下函数来选择住宿在某个 $minvalue 和 $maxvalue 之间的酒店.这样做的最佳方法是什么?

I'd like the following function to select hotels with an accomodation between a certain $minvalue and $maxvalue. What would be the best way to do that?

function gethotels($state_id,$city,$accommodation,$minvalue,$maxvalue,$limit,$pgoffset)
    {
        $this->db->limit($limit, $pgoffset);
        $this->db->order_by("id", "desc");
        $this->db->where('state_id',$state_id);
        $this->db->where('city',$city);

        // This one should become a between selector
        $this->db->where($accommodation,$minvalue); 

        $result_hotels = $this->db->get('hotels');
        return $result_hotels->result();

   }

推荐答案

你应该使用

$this->db->where('$accommodation >=', minvalue);
$this->db->where('$accommodation <=', maxvalue);

我不确定语法，所以如果它不正确，请原谅.
无论如何 BETWEEN 是使用 >=min && 实现的<=最大值
这就是我的例子的意思.

I'm not sure of syntax, so I beg your pardon if it's not correct.
Anyway BETWEEN is implemented using >=min && <=max.
This is the meaning of my example.

看着这个链接，我想你可以写:

$this->db->where("$accommodation BETWEEN $minvalue AND $maxvalue");
