####适用场景

新项目数据迁移用

####Laravel数据迁移例子

1. 结构迁移

<?php

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

class CreateDistrictTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('district', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->integer('level');
            $table->integer('pid');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('district');
    }
}

2. seed

<?php

use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
use Liuyibao\ChinaDistrict\Data;

class DistrictTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // 插入时间不超过5秒钟, 可根据实际键名每一条插入，效率会慢一些
        foreach(Data::fetchByThousand() as $thousandData){
            DB::table('district')->insert($thousandData);
        }
    }
}
