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

    //get_invoice_number(); 
    $this->session->unset_userdata('booking_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

あなたはこの問題を解決するために、理由はとても親切にしMYSQLでONLY_FULL_GROUP_BYオプションの

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

をこの問題に直面しています。

Answer 2

SQLクエリは常にそれでGROUP BY句を持っています。これは、最終結果セットのグループ化されていない他の列を指定します。あなたに

には、以下の発言を照会指摘されています

1. あなたがグループ化しながら、推奨されませんrooms.*を指定しました。
2. グループ化中に特定の列を指定し、その列をGROUP BY節に指定することもできます。たとえば、

、

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
