问题描述

我正在使用Laravel 4.2.我在composer.json

I am using Laravel 4.2. I have the following library loaded in my composer.json

"doctrine/dbal": "2.4.*",

我创建了以下迁移:

class RenameDeliveryNotesColumnOnOrderHeaderTable extends Migration {

    public function up()
    {
        Schema::table('order_header', function(Blueprint $table)
        {
            $table->renameColumn('delivery_notes', 'packing_notes');
        });
    }

}

delivery_notes列类型为text的地方.

运行迁移时，出现以下错误:

When I run the migration, I get the following error:

知道为什么我会收到此错误吗?我应该如何解决这个问题?我需要重命名表中的列.是否有其他方法可以重命名列?

Any idea why I am getting this error? How should I go about fixing this? I need to rename a column in my table. Are there any alternative way to rename the column?
