Also I will give yoy example of laravel 8 group by with where clause and query of group by in mysql. The GROUP BY statement is often used with aggregate functions COUNT()MAX()MIN()SUM()AVG() to group the result-set by one or more columns.

So, let's start how to use group by in laravel 6, laravel 7 and laravel 8.

SQL Query :

Group By Syntax :

SELECT column_names
FROM table_name
WHERE condition
GROUP BY column_names
ORDER BY column_names;

 

 

SELECT COUNT(user_id), country
FROM users
GROUP BY country;

 

Laravel Query :

The “Group By” function belongs to the collection, not eloquent category.

use App\User;
use DB;

public function index()
{
    $users = User::select("*", DB::raw("count(*) as user_id"))
                    ->groupBy('country')
                    ->get();
}

 

Laravel groupBy() with having() query example :

The having method's signature is similar to that of the where method.

$users = DB::table('users')
                ->groupBy('account_id')
                ->having('account_id', '>', 100)
                ->get();

 

 

Laravel groupBy() with Date

Now, I will give you example of group by date or group by year.

DB::table('users')
      ->select(DB::raw('DATE(created_at) as date'), DB::raw('count(*) as views'))
      ->groupBy('date')
      ->get();

 

$users = User::select("*", DB::raw("count(*) as user_count"))
                        ->groupBy(DB::raw("year(created_at)"))
                        ->get();
