I will give you two example of changing data type and rename column name using migration in laravel application.

First of all we need to install "doctrine/dbal" composer package.

Install Composer Package:

After successfully install composer package we can change data type and change column name using migration.

Let's see bellow example:

Migration for main table:

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreatePostsTable extends Migration

{

/**

* Run the migrations.

*

* @return void

*/

public function up()

{

Schema::create('posts', function (Blueprint $table) {

$table->bigIncrements('id');

$table->string('title');

$table->text('body');

$table->boolean('is_publish')->default(0);

$table->timestamps();

});

}

/**

* Reverse the migrations.

*

* @return void

*/

public function down()

{

Schema::dropIfExists('posts');

}

}

Change Data Type using Migration:

body column text data type to long text data type here.

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class ChangePostsTableColumn extends Migration

{

/**

* Run the migrations.

*

* @return void

*/

public function up()

{

Schema::table('posts', function (Blueprint $table) {

$table->longText('body')->change();

});

}

/**

* Reverse the migrations.

*

* @return void

*/

public function down()

{

}

}

Rename using Migration:

rename title column to name changed.

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class ChangePostsTableColumn extends Migration

{

/**

* Run the migrations.

*

* @return void

*/

public function up()

{

Schema::table('posts', function (Blueprint $table) {

$table->renameColumn('title', 'name');

});

}

/**

* Reverse the migrations.

*

* @return void

*/

public function down()

{

}

}
