Database: Query Builder 522
1 $titles = DB::table('roles')->pluck('title');
2
3 foreach ($titles as $title) {
4 echo $title;
5 }
You may also specify a custom key column for the returned array:
1 $roles = DB::table('roles')->pluck('title', 'name');
2
3 foreach ($roles as $name => $title) {
4 echo $title;
5 }
Aggregates
The query builder also provides a variety of aggregate methods, such as count, max, min, avg, and
sum. You may call any of these methods after constructing your query:
1 $users = DB::table('users')->count();
2
3 $price = DB::table('orders')->max('price');
Of course, you may combine these methods with other clauses to build your query:
1 $price = DB::table('orders')
2 ->where('finalized', 1)
3 ->avg('price');
