How to drop column from table using migration in Laravel
In this article we will learn how can you remove column from table in Laravel using migration . As we know it's a better practice to change structure of a table using migration in laravel . So let's see how can you remove a column from table using migration .
Here in this example i have a table named ' items ' in my MySQL Database the structure is given in the below image and from this table we will remove ' catagory ' column using migration .
Step 1 - Create Migration :
First you have to create a migration file to write our code to drop column from table . You can use the following command to create a migration file .
php artisan make:migration drop_catagory_column_from_items_table --table=items
Now this command will create a migration file on your " database/migrations/yourfilename.php " .
Step 2 - Write migration code :
<?php use Illuminate\Database\Migrations\Migration; use Illuminate\Database\Schema\Blueprint; use Illuminate\Support\Facades\Schema; class DropCatagoryColumn extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::table('items', function (Blueprint $table) { if (Schema::hasColumn('items', 'catagory')){ Schema::table('items', function (Blueprint $table) { $table->dropColumn('catagory'); }); } }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::table('items', function (Blueprint $table) { // }); } }
Step 3 - Run migrate command :
Now you have to simply run your migrate command to delete the column from your table .
php artisan migrate
Step 4 - Check your table :
The above code will first check whether the catagory column is exist on your items table or not , if exists it will drop the catagory column otherwise it will leave the table as it is .
