Comment réparer l'erreur dans le projet codeigniter?

Question

Mon message d'erreur dans le cadre de CodeIgniter: Une erreur de base de données Apparu

Error Number: 1140 

In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'hms.rooms.id'; this is incompatible with sql_mode=only_full_group_by 

SELECT `rooms`.*, count(room_no) as total_rooms FROM `rooms` WHERE `room_type_id` = '10' 

Filename: D:/Installed_Apps/OpenServer/OpenServer/domains/hms.loc/system/database/DB_driver.php 

Line Number: 691 

Pourquoi une telle erreur et comment l'éliminer? Dans quoi il peut y avoir un problème dans le code?

Dans ces fonctions, quelque chose ne va pas ou tout est normal?

Voici mon code de contrôleur Book.php où j'utiliser que les fonctions:

    //check availbilty 
    //get_invoice_number(); 
    $this->session->unset_userdata('booking_data'); 
    $this->session->unset_userdata('coupon_data'); 
    $data['page_title']  = lang('make_reservation'); 
    $data['meta_description'] = $this->setting->meta_description; 
    $data['meta_keywords']  = $this->setting->meta_keywords; 
    $data['banners']  = $this->homepage_model->get_banners(); 
    $data['testimonials'] = $this->homepage_model->get_testimonials(); // get 6 testimonials 
    $data['room_types']  = $this->homepage_model->get_room_types_all(); 
    $data['taxes']   = $this->homepage_model->get_taxes(); 
     if(!empty($_GET['room_type'])){ 
      $data['services']   = $this->homepage_model->get_paid_services($_GET['room_type']); 
     } 
     //echo '<pre>'; print_r($data['services']); 
    if(empty($_GET['room_type'])){ 
     $this->render('book/room_types', $data);   
    }else{ 
     check_availability($_GET['date_from'],$_GET['date_to'],$_GET['adults'],$_GET['kids'],$_GET['room_type']); 

     $data['room_type']  = $this->homepage_model->get_room_type($_GET['room_type']); 

     $this->render('book/view', $data);  
    } 


} 

Answer 1

vous êtes face à ce problème en raison de l'option ONLY_FULL_GROUP_BY dans le MYSQL si gentiment mis,

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

pour résoudre le problème.

Answer 2

requête SQL, y compris des fonctions d'agrégation comme COUNT() ou SUM() etc. toujours une clause GROUP BY en elle. Ce qui spécifie les autres colonnes non groupées dans le résultat final.

En vous interrogez les remarques suivantes sont notées:

1. Vous avez spécifié rooms.* qui est pas recommandé tout regroupement.
2. Vous pouvez mentionner des colonnes spécifiques lors du regroupement et spécifier ces colonnes dans la clause GROUP BY également.

Par exemple,

SELECT 
    Count(product_tb.product_id), 
    product_tb.`name`, 
    product_tb.details 
FROM 
    `product_tb` 
WHERE 
product_tb.product_id = 1 
GROUP BY 
    product_tb.`name`, 
    product_tb.details
