laravel5.2如何创建视图表

例：要把mentor_infos和person_infos表创建一个mentor_infos_view视图

　　1 . php artisan make:migration create_mentor_infos_view

2 . class CreateMentorInfosView extends Migration　　{    /**     * Run the migrations.     *     * @return void     */    public function up()    {        DB::statement(‘CREATE OR REPLACE VIEW mentor_infos_view AS            select p.avatar,p.person_name,p.person_phone,p.person_email,           p.person_work_years,p.career,p.person_sex,p.person_birthday,           m.*,i.image_uri           FROM mentor_infos as m           LEFT JOIN person_infos as p ON m.user_id = p.user_id LEFT JOIN sys_images as i ON p.avatar = i.image_id‘);    }

    /**     * Reverse the migrations.     *     * @return void     */    public function down()    {        Schema::drop(‘mentor_infos_view‘);    }　　}

3.php artisan migrate
