How to combine two queries in laravel?

Question

query1:

 $image= DB::table('products_photos')->groupBy('filename')
->get(['filename', DB::raw('MAX(id) as id')]);

This is my query to retreive single image for all the records stored.

query2:

$verifiedValues= priceInfo::join('productDescription', 
'productDescription.productId', '=', 'productPriceDetails.productId')
   ->join('productAdditionalInformation', 
 'productAdditionalInformation.productId', '=', 
'productPriceDetails.productId')
   ->join('products_photos', 'products_photos.productId', '=', 
'productAdditionalInformation.productId')
 ->select('productPriceDetails.SKUID','productDescription.modelName')
   **->select($image)**
        ->where('productPriceDetails.nonliveStatus', '=', 
  "QCVerified")-

>where('productAdditionalInformation.nonliveStatus','=',"QCVerified")
      ->where('productDescription.nonliveStatus','=',"QCVerified")
      ->where('products_photos.nonliveStatus','=',"QCVerified")
      ->where('productPriceDetails.listingStatus','=',"Inactive") 
     ->get();

This is my query where I have joined multiple tables and need to combine the query1 with query2.

error on combining both the queries

Answer 1

IMHO, you have two options. Either you try to merge the two resulting collections by using the merge() method, as it is explained via Laravel :: Combine two DB query objects

Or you use a join to combine the two queries in one single query. To keep your Builder object (without get() ), you may use something like this:

$single_query = DB::table('first_query')
    ->join(DB::raw('('.$second_query->toSQL().') alias'), 'id', 'alias.id')
    ->mergeBindings($second_query)
    ->get();

You may omit the mergeBindungs() clause, if you dont have any parameters.
