Laravel：query选择'as'不适用于where or have

问题描述

我正在努力寻找附近的公司 这是我的查询

$lat = 21.41241750000001;
$long = 39.23094140625001;
return
    $this->model->select('id','lat','long',DB::raw(sprintf(
    '(6371 * acos(cos(radians(%1$.7f)) * cos(radians(`lat`)) * cos(radians(`long`) - radians(%2$.7f)) + sin(radians(%1$.7f)) * sin(radians(`lat`)))) AS `distance`',$lat,$long
)))
    ->having('distance','<',50)
    ->orderBy('distance','asc')
    ->paginate();

永远得到我

sqlSTATE [42S22]：找不到列：1054中的未知列'距离' “具有子句”（sql：从companies中选择count（*）作为聚合 distance = 50）

注意：如果我不进行查询并排序返回和计算的距离 有帮助吗？

解决方法

我有类似的问题。我根据您的情况调整了代码。您可以尝试addSelect。 我认为这段代码是您解决方案的起点：

$lat = 21.41241750000001;
$long = 39.23094140625001;
Companies::addSelect(['distance' => DB::raw(sprintf('(6371 * acos(cos(radians(%1$.7f)) * cos(radians(`lat`)) * cos(radians(`long`) - radians(%2$.7f)) + sin(radians(%1$.7f)) * sin(radians(`lat`)))) AS `distance`',$lat,$long))
                      ])                    
          ->havingRaw('distance < 50')
          ->orderBy('distance','asc')
          ->get(); 

我无法测试；向我们发送反馈！

我的问题出在paginate上，所以我使用了get，但我不知道为什么，所以任何人都可以解释这将是很棒的
