如何使用活动记录查询指定时间之间日期的sql

问题描述

我有一个数据库，我只想提取日期在指定范围内的某些行.我不确定如何在活动记录中正确执行此操作.现在看起来我正在活动记录查询中运行标准的 mysql 查询.我希望这能让你知道我在寻找什么.

I have a database that I want to pull only certain rows that have dates in specified ranges. I'm not sure how to do this properly in active record. Right now it looks like I'm running a standard mysql query inside of an active record query. I hope this gives you the idea of what I'm looking for.

我还希望能够获取包含今天之前的任何内容的行，包括今天和未来 3 天.

I would also like to be able to get rows with anything before today, including today and 3 days in the future.

$query = $this->db->query("SELECT * FROM 'topics_list' . 'topic date' WHERE DATE(order_datetime) BETWEEN '2012-10-01' AND '2012-10-3'");

推荐答案

这就是方法.但根据您在数据库中的 DATE 格式，您必须更改 2012-10-01 和 2012-10-03

this is the way . but according to the DATE format you have in the database you have to change 2012-10-01 and 2012-10-03

$this->db->select('*');
$this->db->from('topics_list');
$this->db->where('order_datetime <','2012-10-03');
$this->db->where('order_datetime >','2012-10-01');

$result = $this->db->get();
