Connection.php第647行中的Laravel QueryException：SQLSTATE [42000]：语法错误或访问冲突

Question

我试图运行以下带有查询的查询构建器。

$products = \DB::table('users')
            ->join('products','products.auth_id','users.id')
            ->leftjoin('buys','products.id','buys.product_id')
            ->select('products.*','users.avatar',DB::raw('COUNT(buys.product_id) as total_sells') ) 
            ->groupBy('products.id')               
            ->where('products.status','=','1')
            ->take(20)
            ->paginate(4);

Where in products.id could be there in buys table or not..

但是我越来越关注错误。 我将database.php mysql array from strict = true to false 。

QueryException in Connection.php line 647:
SQLSTATE[42000]: Syntax error or access violation: 1055 'cart.products.name' isn't in GROUP BY

Answer 1

尝试

$products = \DB::table('users')
->selectRaw('products.*,users.avatar, COUNT(buys.product_id) as total_sells') 
->where('products.status','=','1')
        ->join('products','products.auth_id','=', 'users.id')
        ->leftjoin('buys','products.id','buys.product_id')
        ->groupBy('products.id')                    
        ->take(20)
        ->get();

我不确定分页功能是否会查询生成器。
