How to use database migration in laravel

Hello World, Welcome to my website. Today I am going to discuss how to use database migration in laravel. For a better understanding of database migration, I have created this tutorial with example.

I have divided this tutorial into the following parts.

  • What is migration?
  • How to Create a migration file?
  • How to Run Migration?

What is migration?

Migration is a file which Creates or modify the database tables.

Migration Up Method

Whenever new migration created then the system grabs this migration and run the up method. it helps to do the things.

Migration Down Method

If someone wants to roll back his most recent set of migrations then down method will run by the system. It helps to undo the things.

Laravel comes with “create user table” migration. Following is the code of this migration file.


use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
     * Run the migrations.
     * @return void
    public function up()
        Schema::create('users', function (Blueprint $table) {

     * Reverse the migrations.
     * @return void
    public function down()

In the above code, you can see that the up method is creating the table and defining columns in this table and down method drop this table.

Please define your database credentials in .env file

Laravel has lots of command-line tools for working with the app and generate files. In these commands, One command allows creating the migration file. For example, we want to create the above the user table. We will run the following command to create a migration file.
