如何在where子句[Codeigniter]中使用连接

Question

您好我正在尝试在codeigniter中的where子句中使用concatenation在mysql中使用Equivelent

SELECT * FROM `tblstaff` WHERE concat_ws(' ',firsname,lastname) like '%Firstname lastname%'

我尝试在codeigniter中执行此操作，但无法正常工作

$admin = 'Firstname lastname';

$CI =& get_instance();
$CI->db->where('firstname'.' '.'lastname',$admin);

return $CI->db->get('tblstaff')->row()->default_language;

有任何想法吗

Answer 1

未经测试但尝试改变

$CI->db->where('firstname'.' '.'lastname',$admin);

至

 $CI->db->where("CONCAT_WS(' ',firsname,lastname) LIKE '%".$admin."%'", NULL, FALSE);

Answer 2

尝试codeigniter的查询构建器$this->db->like如下：

$admin = 'Firstname lastname';

$CI->db->like("CONCAT_WS(' ',firsname,lastname)",$admin,"both");
