Group_concat - laravel eloquent

问题

please I want to use group_concat in a query using eloquent and not raw queries.

here is the code which i tried to execute and did't work for me:

commands::join('products', 'products.id', '=','commands.idproduct')
->select('commands.username','**group_concat(products.name)**')
->group by ('commands. username')
->get();

Thanks in advance :)

回答1:

I just used use DB; and in my query I used DB::raw('group_concat(products.name)') !!

回答2:

This worked for me

$list = TableName::where('user_id', 'user_001'
        ->groupBy('user_id')
        ->groupBy('subscription_id')
        ->select('user_id','subscription_id','type')
        ->selectRaw('GROUP_CONCAT(holiday) as holidays')
        ->get();

use Illuminate\Support\Facades\DB;

$sql = 'SELECT GROUP_CONCAT(holiday) as holidays, user_id,subscription_id, type FROM TableName 
        where vendor_id = 'user_001' GROUP BY user_id, subscription_id;';
$list = DB::select($sql, []);

Best example for it..

 
ModelName::select('ID', DB::raw('CONCAT(First_Name, " ", Last_Name) AS full_name'))
           ->get()
           ->toArray();

Result

回答4:

or just replace

->select('commands.username','**group_concat(products.name)**')

with

->selectRaw('commands.username, **group_concat(products.name)**')

回答5:

This worked for me: (9.0+)

DB::raw('string_agg(products.name, \',\') as products')

You will need to use Illuminate\Support\Facades\DB; for this.

$data=\DB::table('paging_config') ->leftjoin('paging_groups', 'paging_config.page_group', '=', 'paging_groups.page_number') ->leftjoin('spk_mnt', 'paging_groups.ext', '=', 'spk_mnt.stn_no') ->select('paging_config.page_group','paging_groups.ext', 'spk_mnt.stn_status') ->selectRaw('GROUP_CONCAT(DISTINCT description) as description') ->where('paging_config.page_group','=','paging_config.page_group') ->groupBy('paging_config.description')

        ->get();
