How to Add a Column or Columns To Existing Table In Laravel
In this step by step guide I will demonstrate you how to add new columns or columns to an existing table using Laravel migration.
Laravel Migration:
- Add a single Column an existing table
- Add Multiple Columns in Existing Table
- Available Column Types
Add a single Column an existing table
Below is the example command to add single column to existing table.
|
1 |
php artisan make:migration add_type_to_notes |
It will create an add_type_to_notes file in the migration folder. It should be like this-
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 |
<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class AddTypeToNotes extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::table('notes', function (Blueprint $table) { $table->string('note_type')->nullable(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::table('notes', function (Blueprint $table) { $table->dropColumn(['note_type']); }); } } |
Run Migration Command
Now, run the following command to migrate table schema,
|
1 |
php artisan migrate |
Add Multiple Columns in Existing Table
Below is the example command to add multiple column to existing table.
|
1 |
php artisan make:migration add_multiple_column_to_notes |
The above command will create a migration file, so go to database/migration folder and open your file and add column according to you:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 |
<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class AddMultipleColumnToNotes extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::table('notes', function (Blueprint $table) { $table->string('short_description')->nullable(); $table->string('type')->nullable(); $table->string('long_description')->nullable(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::table('notes', function (Blueprint $table) { $table->dropColumn(['short_description', 'type', 'long_description']); }); } } |
Finally, run the below-given command for adding columns in your database table:
|
1 |
php artisan migrate |
