How to rename a column in Laravel migration file?

To rename a column in a Laravel migration, you can use the renameColumn method on the Blueprint instance in your migration file.

Here’s an example of how you can use the renameColumn method to rename a column called old_column to new_column in a table:

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

class RenameColumnInTable extends Migration
{
    public function up()
    {
        Schema::table('table', function (Blueprint $table) {
            $table->renameColumn('old_column', 'new_column');
        });
    }

    public function down()
    {
        Schema::table('table', function (Blueprint $table) {
            $table->renameColumn('new_column', 'old_column');
        });
    }
}

You can then run the migration using the php artisan migrate command.

Keep in mind that the renameColumn method is not available on all database systems, so you may need to use a different method depending on your database server.

If you want to rename multiple columns at once, you can use the renameColumn method multiple times within the same migration. For example:

class RenameColumnsInTable extends Migration
{
    public function up()
    {
        Schema::table('table', function (Blueprint $table) {
            $table->renameColumn('old_column_1', 'new_column_1');
            $table->renameColumn('old_column_2', 'new_column_2');
            $table->renameColumn('old_column_3', 'new_column_3');
        });
    }

    public function down()
    {
        Schema::table('table', function (Blueprint $table) {
            $table->renameColumn('new_column_1', 'old_column_1');
            $table->renameColumn('new_column_2', 'old_column_2');
            $table->renameColumn('new_column_3', 'old_column_3');
        });
    }
}

This will rename three columns in the table: old_column_1 to new_column_1, old_column_2 to new_column_2, and old_column_3 to new_column_3.
