生成迁移

参考文档

php artisan make:migration upgrade_to_v15

class UpgradeToV15 extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {

        //调用artisan
        \Illuminate\Support\Facades\Artisan::call('test:xxxx');

        //使用SQL更新数据
        $sql = "UPDATE `users` SET `name` = 'root' WHERE (`id` = 1)";
        DB::statement($sql);

        //调用函数
        $this->addSth();

        //更改字段
        if (!Schema::hasColumn('users', 'phone')) {
            Schema::table('users', function (Blueprint $table) {
                $table->string('phone')->default(null)->comment('电话');
            });
        }

        //新增表
        Schema::create('asset_websites_extra', function (Blueprint $table) {
            $table->collation = 'utf8mb4_general_ci';
            $table->bigIncrements('id');
            $table->integer('website_id');
            $table->timestamps();
            $table->index('website_id', 'website_id');

        });

    }

    public function addSth() {
        //todo sth.
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        //此处操作危险，最好不要进行什么删表等危险操作， 但可以删除一些缓存

    }
}

运行迁移

php artisan migrate
