        插入多个时要再加一个数组
        ['title'=>'title','name'=>'name']
        ['title'=>'title']
        ['title'=>'title']
        ])

        插入时要想得到ID
        DB::table('tablename')->insertGetId(['title'=>'titles'])

        更新数据要有ID
        DB::table('tablename')->where('id',1)->update(['title'=>'titles'])

        删除数据
        DB::table('tablename')->where('id',1)->delete();

        查询数据
        DB::table('tablename')->get();  得到全部的值
        DB::table('tablename')->get(['title']); 只查询title的值
        DB::table('tablename')->first();  只拿第一个
        DB::table('tablename')->orderBy('id','desc')->first(); 根据id排序
        DB::table('tablename')->where('id','!=',2)->get(); 不等于2
        DB::table('tablename')->where('id','!=',2)->where('id','>',5)->get(); 可以使用多个where
        DB::table('tablename')->where('id','!=',2)->OrWhere('id','>',5)->get(); 或者
        DB::table('tablename')->whereBetween('id',[2,5])->get();  闭包之间
        DB::table('tablename')->whereIn('id',[2,5,9])->get();
        DB::table('tablename')->whereNotIn('id',[2,5,9])->get();
        DB::table('tablename')->whereNull('id')->get();  为空的话就可以查询出来
        DB::table('tablename')->take(3)->get();  只查询3个
        DB::table('tablename')->limit(3)->get();  只查询3个
        DB::table('tablename')->skip(2)->take(3)->get();  只查询3个跳过第二个
        DB::table('tablename')->where('id','!=',2)->pluck('title'); 只返回它的title
        DB::table('tablename')->count();  有多少条记录
        DB::table('tablename')->max('id');
        DB::table('tablename')->min('id');
        DB::table('tablename')->avg('id');
        DB::table('tablename')->sum('id');

取得关联值
                Post::find(2)->comment  就可以得到Comment这张表的内容   //这样查询一个是可以的  查询多个就要设置预载入
            查询多个
                Post::with('comment')->get();
                Post::with(['comment'=>function($query){$query->where('id','>',2)}])->get();  加条件
