php - Codeigniter 请求 sql 但我的代码返回错误

Question

我希望显示 SQL 请求的结果，但我的代码返回了一个我无法解决的错误。如果有人能帮助我，我将不胜感激。

我正在使用 Codeigniter。

<?php defined('BASEPATH') OR exit('No direct script access allowed');

class Dropdown extends CI_Controller {

    public function __construct()
    {
        parent::__construct();  
    }

    public function index()
    {   
        $data['title']='Dependent Dropdown List';
        $data['page']='index';
        $data['MANUFACTURERS'] = $this->book_model->get_author();
        $this->load->view('index', $data);
    }


    public function ctest()
    {
        $data['MODELS'] = $this->book_model->test();
        $this->load->view('ajax_get_book',$data);
    }

}
?>

<?php defined('BASEPATH') OR exit('No direct script access allowed');

class book_model extends CI_Model {


    function __construct(){
        // Call the Model constructor
        parent::__construct();        
    }
    public function test() {   
        $lang = 6;
        $code = 533001410;

        $query = $this->db->query("SELECT DISTINCT
         IF (ART_LOOKUP.ARL_KIND IN (3, 4), BRANDS.BRA_BRAND, 
         SUPPLIERS.SUP_BRAND) AS 
         BRAND, ART_LOOKUP.ARL_SEARCH_NUMBER AS NUMBER, ART_LOOKUP.ARL_KIND,    
         ART_LOOKUP.ARL_ART_ID, DES_TEXTS.TEX_TEXT AS ART_COMPLETE_DES_TEXT

         return $query->result();
    }
}
?>

Error Number: 1055

Answer 1

您的 GROUP BY 子句不包含 SELECT 中的所有非聚合字段，例如 ART_LOOKUP.ARL_KIND、ART_LOOKUP.ARL_ART_ID、DES_TEXTS.TEX_TEXT AS ART_COMPLETE_DES_TEXT。

也许可以将这些字段添加到您的 GROUP BY 中？
