laravel db อยู่ก่อน
if (DB::table('orders')->where('finalized', 1)->exists()) {
// ...
}
if (DB::table('orders')->where('finalized', 1)->doesntExist()) {
// ...
}
laravel ถ้าฐานข้อมูลมีโต๊ะ
if (Schema::hasTable('users')) {
// The "users" table exists...
}
if (Schema::hasColumn('users', 'email')) {
// The "users" table exists and has an "email" column...
}
