webman-查詢構造器-orderBy,随机排序的用法

发布时间：2022-02-05 12:32:09编辑：雪饮阅读（）

 實例：

    public function index(Request $request)
    {

        ini_set('memory_limit','4096M');
       //orderBy
        $data= Db::table('ecms_news')
            ->orderBy('username', 'desc')
            ->get();
        $orderBy=isset($data[0]) ? $data[0] : [];

        //随机排序
        $data = Db::table('ecms_news')
            ->inRandomOrder()
            ->first();

        $all=compact("orderBy","data");
        var_dump($all);

        return response("ok");
    }
 構造的sql：
select * from `phome_ecms_news` order by `username` desc
select * from `phome_ecms_news` order by RAND() limit 1
tips：随机排序会对服务器性能影响很大，不建议使用
