如何在Codeigniter中计算group_concat [英] How to calculate group_concat in codeigniter

问题描述

我想对产品名称进行分组..但是它在我的视图页面中显示未定义的索引产品名称..我不知道我在哪里犯错..请帮助我对产品名称进行分组..

I want to groupconcat product name..but it displaying undefined index product name in my view page..I don't know where i am making mistake..please help me to groupconcat product name..

控制器代码:

$this->db->select('GROUP_CONCAT(prdtname)', false);
$this->db->from('purchaseitem');
$this->db->group_by('vno');
$query1=$this->db->get()->row_array();
$data['query1']= $query1;

我在本地主机上的sql中尝试了groupconcat，它给了我预期的结果..但我不知道在转换为codeigniter时我在哪里做错了..请帮助我解决这个问题..

I tried groupconcat in sql on my localhost it gives me an expected result..but i don't know where i had done mistake in converting to codeigniter..please help me to resolve this..

推荐答案

控制器代码:

$this->db->select('GROUP_CONCAT(prdtname)as itemname',false);
$this->db->from('purchaseitem');
$this->db->group_by('vno');

查看页面:

<td><?=$row['itemname'];?></td>
