codeigniterが同じクエリでサブテーブルから複数の値を取得する

Question

同じクエリでサブテーブルから複数の値をフェッチしようとしているときに問題が発生しました。私はdealdetailsとdealImagesテーブルを持っています。dealImagesは、deal-idからdealdetailsテーブルまでの複数の値を含むことができます。 、のような常に次に、選択クエリにGROUP_CONCATを追加

 [deal_submittedby] => 0 
     [dealType] => 1 
     [totalavailabledeals] => 0 
     [numberofdealused] => 0 
     [showinhomescreen] => 1 
     [showinmenu] => 0 
     [isHomeScreenBigDeal] => 1 
     [imageId] => 22 
     [imageUrl] => http://localhost/codeIgniter/uploads/cover_image/storeimages/general/general_1493562480.momo.jpg 
     [thumbImage] => http://localhost/codeIgniter/uploads/cover_image/storeimages/thumb/thumb_1493562480.momo.jpg 
     [imageOrder] => 1 
     [addedOn] => 2017-04-30 14:28:43 
     [imageobjId] => 1493562480 
     [normalimageurl] => http://localhost/codeIgniter/uploads/cover_image/storeimages/normal/normal_1493562480.momo.jpg 
     [imgobjext] => momo.jpg 
     [imgobject] => 1493562480.momo.jpg 
     [imgisdefault] => 1

ようdealImagesから単一の値を返している

$dealDetailsArray  = array(); 
     $this->db->select('d.dealId,d.dealTitle,d.slug,d.dealDetails,d.extraDetails,d.aditionalDetails,d.status,d.dateAdded,d.categoryId,d.dealSubCategory,d.siteId,d.dealBrandId,d.isPinned,d.priceId,d.price,d.startDate,d.startTime,d.endDate,d.endTime,d.addedTime,d.dealUrl,d.adminAffiliatePrice,d.cashbackType,d.cashbackAmountType,d.cashbackAmount,d.shippingType,d.NumberOfClicked,d.priceType,d.discountPrice,d.discountPercentage,d.deal_location,d.howtousethisoffer,d.cancellationpolicy,d.deal_submittedby,d.dealType,d.totalavailabledeals,d.numberofdealused,d.showinhomescreen,d.showinmenu,d.isHomeScreenBigDeal,di.imageId,di.imageUrl,di.thumbImage,di.imageOrder,di.status,di.dealId,di.addedOn,di.imageobjId,di.normalimageurl,di.imgobjext,di.imgobject,di.imgisdefault'); 
     $this->db->from('dealdetails as d'); 
     $this->db->join('dealImages di', 'di.dealId = d.dealId','left'); 
     $this->db->where('d.endTime >= ',date('Y-m-d H:i:s')); 
     $this->db->group_by('d.dealId'); 
     $this->db->order_by("d.dealId", "desc"); 
     $query = $this->db->get(); 

     if($query->num_rows()>0) { 
      $dealDetailsArray = $query->result_array(); 
      $query->free_result(); 
     } 
     return $dealDetailsArray; 

をクエリを書くことは（、）コンマで値を返すように

コードを分離：

$dealDetailsArray  = array(); 
     $this->db->select('d.dealId,d.dealTitle,d.slug,d.dealDetails,d.extraDetails,d.aditionalDetails,d.status,d.dateAdded,d.categoryId,d.dealSubCategory,d.siteId,d.dealBrandId,d.isPinned,d.priceId,d.price,d.startDate,d.startTime,d.endDate,d.endTime,d.addedTime,d.dealUrl,d.adminAffiliatePrice,d.cashbackType,d.cashbackAmountType,d.cashbackAmount,d.shippingType,d.NumberOfClicked,d.priceType,d.discountPrice,d.discountPercentage,d.deal_location,d.howtousethisoffer,d.cancellationpolicy,d.deal_submittedby,d.dealType,d.totalavailabledeals,d.numberofdealused,d.showinhomescreen,d.showinmenu,d.isHomeScreenBigDeal,di.imageId,di.GROUP_CONCAT(di.imageUrl) AS imageUrl,di.thumbImage,di.imageOrder,di.status,di.dealId,di.addedOn,di.imageobjId,di.normalimageurl,di.imgobjext,di.imgobject,di.imgisdefault'); 
     $this->db->from('dealdetails as d'); 
     $this->db->join('dealImages di', 'di.dealId = d.dealId','left'); 
     $this->db->where('d.endTime >= ',date('Y-m-d H:i:s')); 
     $this->db->group_by('d.dealId'); 
     $this->db->order_by("d.dealId", "desc"); 
     $query = $this->db->get(); 

     if($query->num_rows()>0) { 
      $dealDetailsArray = $query->result_array(); 
      $query->free_result(); 
     } 
     return $dealDetailsArray;
