[英]Rewrite MySQL query using Codeigniter Active record
I have started CodeIgniter not long ago. 我不久前已经启动CodeIgniter。 Can some tell me how to rewrite this query 有人可以告诉我如何重写此查询
SELECT question.timestamp AS question_time, reply.timestamp AS reply_time,
(SELECT DATEDIFF(reply_time, question_time)) AS time_used_to_reply
FROM question JOIN reply ON question.id = reply.question_id WHERE question.company_id=someid
using the activerecord 使用活动记录
Also any tutorial to quickly understand activerecord would be very appreciated. 此外,任何快速理解activerecord的教程都将不胜感激。 Thanks 谢谢
After many researches, I ended up writing my own active record script. 经过大量研究,我最终编写了自己的活动记录脚本。
$this->db->select(array('DATEDIFF(reply.timestamp, question.timestamp)'))
->from('question')
->join('reply', 'question.id = reply.question_id')
->where('question.company_id', $company_id);
Thanks 谢谢
