Sometimes in laravel we wanted to run raw query like select, insert, delete, alter etc. Laravel have multiple ways to run a raw query using select, prepare or statement method in db builder. In this article i will show you to run the raw query in laravel.

To understand this we will take simple examples of multiple solutions. So here is the list to execute the raw query using DB facade in laravel

  1. Select
  2. Insert
  3. Update
  4. Delete
  5. Statement
  6. unprepared
  7. raw
  8. selectRaw
  9. whereRaw
  10. orderByRaw
  11. groupByRaw
  12. havingRaw

As you can we have multiple ways to create raw query and use of it in different cases.

Select() method of DB class

Select method is used to execute select statement in db builder as below

 
public function index()
{
    $users = \DB::select('SELECT * from users');

}

Output of above code:

array:1 [
  0 => {#1268 ▼
    +"id": 1
    +"name": "Aman"
    +"email": "Aman@yopmail.com"
    +"email_verified_at": null
    +"password": "2121212"
    +"remember_token": null
    +"created_at": null
    +"updated_at": null
  }
]

    dd($user);
}
