如何在laravel中修剪具有固定长度的二进制列的空值

php artisan make:migration trim_binary_column --table=your_table_name

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

class TrimBinaryColumn extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        DB::statement('UPDATE your_table_name SET your_binary_column = TRIM(your_binary_column)');
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        // 如果需要回滚迁移操作，可以在这里撤销修剪操作
    }
}

php artisan migrate
